I have a WebService which return DateTime Field.
I get a result /Date(1379048144000)/ but
i want just 1379048144000 how can i achieve that.
[WebMethod]
public DateTime GetServerDate()
{
return DateTime.Now;
}
by setting Header Content-Type: application/json; charset=utf-8; i got a result like /Date(1379048144000)/.
You could change your WS to return a long with the value of the DateTime. The value to return is the number of milliseconds since the Unix Epoch (01/01/1970). This could be done with an extension method on DateTime something like:
public static class DateTimeExtensions
{
...
private static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1);
public static long ToUnixTime(this DateTime dateTime)
{
return (dateTime - UnixEpoch).Ticks / TimeSpan.TicksPerMillisecond;
}
...
}
And your web service method might look something like:
public long GetMyDate(...)
{
DateTime dateTime = ...;
return dateTime.ToUnixTime();
}
with Json.NET :
string date = Newtonsoft.Json.JsonConvert.SerializeObject(DateTime.Now);
in client side you can use this function to show a right date to client(I use it on my projects):
function parseJsonDate(jsonDate) {
var offset = new Date().getTimezoneOffset() * 60000;
var parts = /\/Date\((-?\d+)([+-]\d{2})?(\d{2})?.*/.exec(jsonDate);
if (parts[2] == undefined) parts[2] = 0;
if (parts[3] == undefined) parts[3] = 0;
d = new Date(+parts[1] + offset + parts[2] * 3600000 + parts[3] * 60000);
date = d.getDate() + 1;
date = date < 10 ? "0" + date : date;
mon = d.getMonth() + 1;
mon = mon < 10 ? "0" + mon : mon;
year = d.getFullYear();
return (date + "." + mon + "." + year);
};
This function is return right date in format: dd.mm.yyyy, but you can change it if you need. I hope that I help you.
U can always solve your problem when sending a date in a JSON object to JS by converting the date as follows:
var myJSDate = (new Date(parseInt(obj.MyDate.substr(6)))).toJSON();
Where obj.Date contains the date you wanna format.
Then u'll get something like this: "2013-10-25T18:04:17.289Z"
U can always check it in Chrome console by writing:
(new Date()).toJSON();
Hope this helps!
There are two solutions:
client side:
function ToJavaScriptDate(value) {
var pattern = /Date\(([^)]+)\)/;
var results = pattern.exec(value);
var dt = new Date(parseFloat(results[1]));
return (dt.getMonth() + 1) + "/" + dt.getDate() + "/" + dt.getFullYear();
}
It is possible to need alsou to convert into data object
var date = new Date(xxx)
Server side:
Newtonsoft.Json.JsonConvert.SerializeObject(your_object)
Simply write like this to convert your date string in JSON format.
date = "{" + date + "}";
try regex:
var jsonDate = #"/Date(1379048144000)/";
var regex = /-?\d+/;
var jsonDate = re.exec(jsonDate);
var dateOriginal = new Date(parseInt(m[0]));

Trying to figure out how to add a century prefix (19 or 20) to a birth date. Does anyone see how to write this in a better way?
public string GetCenturyPrefix(string socSecNo)
{
string prefix = string.Empty;
try
{
var currentDate = DateTime.Now;
var birthDayTemp = socSecNo.Substring(0, 6);
var yy = birthDayTemp.Substring(0, 2);
var mm = birthDayTemp.Substring(2, 2);
var dd = birthDayTemp.Substring(4, 2);
birthDayTemp = yy + "-" + mm + "-" + dd;
var birthDay = Convert.ToDateTime(birthDayTemp);
var totalDays = currentDate - birthDay;
var age = totalDays.TotalDays / 365;
var yearsAfter2000 = Convert.ToInt32(currentDate.Year.ToString().Substring(2, 2));
if (age > yearsAfter2000)
{
prefix = "19";
}
else
{
prefix = "20";
}
}
catch (Exception)
{
}
return prefix;
}
Don't use Substring to parse a string value into a DateTime. .Net has very robust methods created for you to do this conversion.
Here I'm using DateTime.TryParseExact(), which lets me specify the exact format I expect dates values to be provided in. The method returns true or false indicating if the value is in that supplied format. No need to use exceptions to control logic flow.
public string GetCenturyPrefix(string socSecNo)
{
// Check if you're able to parse the incoming value
// in the format "yyMMdd".
if (!DateTime.TryParseExact(socSecNo, "yyMMdd", CultureInfo.InvariantCulture,
DateTimeStyles.None, out DateTime parsedDateTime))
{
// Do something if the input can't be parsed in that format.
// In this example I'm throwing an exception, but you can also
// return an empty string.
throw new Exception("Not valid date format");
}
// Extract only the Year portion as a 4 digit string,
// and return the first 2 characters.
return parsedDateTime.ToString("yyyy").Substring(0, 2);
}
You can do it like (year/100)+1 but put {0:n0} format to your .ToString("{0:n0}") this could be the logic and for the if else it can stay like that. This should be working for any century as I tried on calculator.
I want to show my date field in a textbox which is coming from Oracle database.
The scenario is, my date stored in DB column is 01-12-17 and its datatype is date.
and while binding it is coming as 1-11-17 I don't know why it's happening like this.
Here is my binding code.
if (getJSONValue.LAUNCH_DATE != "" || getJSONValue.LAUNCH_DATE != null) {
var newDate = new Date(getJSONValue.LAUNCH_DATE);
var day = newDate.getDate();
var month = newDate.getUTCMonth() + 1;
var year = newDate.getFullYear();
$('#txtLaunchDate').val(day + "-" + ((month)) + "-" + year.toString().substr(-2));
}
else {
$('#txtLaunchDate').val("");
}
When you call this :
var newDate = new Date(getJSONValue.LAUNCH_DATE);// if your date is 01-12-2017
the result is : Thu Jan 12 2017 00:00:00
It switches month and day info.
And as you try to add two values it contatenates :
var month = newDate.getUTCMonth() + 1; //returns 1 + 1 as string and the result is 11.
That that is why you see 1-11-17.
If you want a simple solution,
var str = getJSONValue.LAUNCH_DATE; //"01-12-2017";
var array = str.split("-");
var day = array[0];
var month = array[1];
var year = array[2].substr(2);
var dateStr = day + "-" + month + "-" + year;
Use getMonth instead of getUTCMonth:
var newDate = new Date('2017-12-01T00:00:00');
var day = newDate.getDate();
var month = newDate.getMonth()+1;
var year = newDate.getFullYear();
alert(day + "-" + ((month)) + "-" + year.toString().substr(-2));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Try this
var month = (Number(newDate.getUTCMonth()) + 1);
Hei,
I want to add to a day wrote in a unix format a day or two.
I use DateTime.Now converted to Unix.The idea is if the order is finished before 16:00 the order will be shipped on next working day (datetime.now)+1. If the order is finished after 16:00 the order will be shipped on (datetime.now)+2.
This will be only on working day. If is weekend next working day will be on Monday.
DateTime normalSF;
MyDateTime normal = new MyDateTime();
MyDateTime normal1 = new MyDateTime();
date_ship_form = normal.ConvertToUnix(DateTime.Now);
normalSF = normal1.ConvertToDate(Convert.ToInt64(date_ship_form));
lblDateSF.Text = ((normalSF.Day < 10) ? "0" : "") + normalSF.Day.ToString() + "/" + ((normalSF.Month < 10) ? "0" : "") + normalSF.Month.ToString() + "/" + normalSF.Year.ToString();
This is how I use DateTime Unix in my code.
You can try this
var currdate = DateTime.Now;
long myStartDate = currdate.ToTimeStamp();
var resdate = myStartDate.AddDays(2);
long finaldate = resdate.ToTimeStamp();
You can try to convert the Unix timestamp to DateTime like this:
public static DateTime myDate(double unixTime)
{
System.DateTime dt = new DateTime(1970,1,1,0,0,0,0,System.DateTimeKind.Utc);
return dt.AddSeconds(unixTime).ToLocalTime();
}
I am using the fullcalendar,
but in IE 10 or 11 the events are not render correct,
I have this:
public static List<DiaryEvent> LoadAllAppointmentsInDateRange(double start, double end)
{
var fromDate = ConvertFromUnixTimestamp(start);
var toDate = ConvertFromUnixTimestamp(end);
using (LolaBikeContext ent = new LolaBikeContext())
{
var rslt = ent.AppointmentDiarys.Where(s => s.DateTimeScheduled >= fromDate && System.Data.Entity.DbFunctions.AddMinutes(s.DateTimeScheduled, s.AppointmentLength) <= toDate);
List<DiaryEvent> result = new List<DiaryEvent>();
foreach (var item in rslt)
{
DiaryEvent rec = new DiaryEvent();
rec.ID = item.Id;
rec.SomeImportantKeyID = item.SomeImportantKey;
rec.StartDateString = item.DateTimeScheduled.ToString("MMMM/dd/yyyy"); // "s" is a preset format that outputs as: "2009-02-27T12:12:22"
rec.StarEvent = item.DateTimeScheduled.ToString("HH:mm"); // ParseExact(start, "HH:mm", CultureInfo.CurrentCulture).ToString(); //item.DateTimeScheduled.ToString("MMMM/dd/yyyy");
rec.EndDateString = item.DateTimeScheduled.AddMinutes(item.AppointmentLength).ToString("yyyy-MM-ddTHH\\:mm\\:ss.fffffffzzz");// "yyyy-MM-ddTHH:mm:ss.fffZ"); // field AppointmentLength is in minutes
rec.Title = item.Title;// +" - " + item.AppointmentLength.ToString() + " mins";
rec.AppointmentLength = item.AppointmentLength.ToString();
rec.StatusString = Enums.GetName<AppointmentStatus>((AppointmentStatus)item.StatusENUM);
rec.StatusColor = Enums.GetEnumDescription<AppointmentStatus>(rec.StatusString);
string ColorCode = rec.StatusColor.Substring(0, rec.StatusColor.IndexOf(":"));
rec.ClassName = rec.StatusColor.Substring(rec.StatusColor.IndexOf(":") + 1, rec.StatusColor.Length - ColorCode.Length - 1);
rec.StatusColor = ColorCode;
result.Add(rec);
}
return result;
}
}
and especially this line:
rec.EndDateString = item.DateTimeScheduled.AddMinutes(item.AppointmentLength).ToString("yyyy-MM-ddTHH\\:mm\\:ss.fffffffzzz");// is not rendering correct.
I have read that it has to be in: ISO 8601, so I have looked at this thread:
Given a DateTime object, how do I get an ISO 8601 date in string format?
but that doesnt work. IE is rendering the events not correct
Thank you!!
see the different pictures
The correct image:
I think youare missing the "s" format specifier, which is described as Sortable date/time pattern; conforms to ISO 8601
The EventStart comes in ISO 8601 format and you will need to convert it. you can follow this example to convert current to ISO 8601:
DateTime.UtcNow.ToString ( "s", System.Globalization.CultureInfo.InvariantCulture )
Here's a post about that : Link
As for your code try this instead for your startdatestring and enddatestring:
rec.StartDateString = item.DateTimeScheduled.ToString("s");
rec.EndDateString = item.DateTimeScheduled.AddMinutes(item.AppointmentLength).ToString("s");
How do I covert JavaScript string "5:00 PM" to DateTime or TimeSpan when it get send to the MVC controller. I am using
bootstrap-timepicker
// usage
<script type="text/javascript">
$('#timepicker1').timepicker();
</script>
Javascript payload
{
Skip: 0
Status: []
Take: 15
DueTime: "1:00 PM" // keep in mind that this is a string
}
Server Object would be something like
class TimeSheet
{
public TimeSpan DueTime;
}
Use DateTime.Parse. Convert on server(on controller) when your string would transmit with your time.
http://msdn.microsoft.com/ru-ru/library/system.datetime.parse(v=vs.110).aspx
Okay so I read everyhting wrong hence the deleted answer.. !
But I'm not giving up ;)
Your bootstrap-timepicker, will give you a time as this "1:00 PM".
But before that we are going to look on the serverside to see what we can parse into a datetime object.
This is C# for parsing datetime.
string dateString, format;
DateTime result;
CultureInfo provider = CultureInfo.InvariantCulture;
dateString = "15/08/2000 16:58"
format = "dd/MM/yyyy HH:mm"
result = DateTime.ParseExact(dateString, format, provider);
Now as you se your string wont look like that I'm going to assume that you want todays date!
This is function I tend to use most of the times when converting, to 24H clock.
function ConvertTimeformat(str) {
var time = str;
var hours = Number(time.match(/^(\d+)/)[1]);
var minutes = Number(time.match(/:(\d+)/)[1]);
var AMPM = time.match(/\s(.*)$/)[1];
if (AMPM == "PM" && hours < 12) hours = hours + 12;
if (AMPM == "AM" && hours == 12) hours = hours - 12;
var sHours = hours.toString();
var sMinutes = minutes.toString();
if (hours < 10) sHours = "0" + sHours;
if (minutes < 10) sMinutes = "0" + sMinutes;
//Creating the todays date in the right format
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1;//January is 0!`
var yyyy = today.getFullYear();
if(dd<10){dd='0'+dd}
if(mm<10){mm='0'+mm}
var todaysdate = dd+'/'+mm+'/'+yyyy +" " ; //<--I added an extra space!
var hoursNminutes = sHours + ":" + sMinutes
//CREATE THE RIGHT FORMAT FOR DATE.PARSEXACT "dd/MM/yyyy HH:mm"
var dateToParse = todaysdate + hoursNminutes
return dateToParse;
}
To Use the function do like this!
//Call it and provide your bootstrap time. And make it return to a variable
var dateToBeSentToServer = ConvertTimeformat("1:00 PM");
//OR With the bootstraptime as a variable
var dateToBeSentToServer = ConvertTimeformat(timevariable);
Now you can send dateToBeSentToServer to your serverside for parsing!
