    Format dato to UTS (seconds since 1/1/1970)

    Hi all

    I want to format a datePicker date to UTS Unix time....

    @umbraco.library.FormatDateTime(minDato, "dd/MM/yyyy");

    I guess its something with DateAdd to do ...but there ends my ideas :-)

    var utsDato = umbraco.library.DateAdd(@minDato,"s","1/1/1970");

    Anyone who knows or already have done this?

    TIA

    Hi Tia

    this is a bit more of a generic .net/c# question, but if you have a date time and are using .net 4.6+ you can ask for it directly. 

    var date = new DateTime(2018, 9, 3);
var offset = new DateTimeOffset(date);
var unixTime = offset.ToUnixTimeSeconds();

    however if you are using a .net version eariler then .net 4.6 you have to do it a bit of a more long winded way.

    var date = new DateTime(2018, 9, 3, 18, 32, 0, DateTimeKind.Local);
var epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
var unixDateTime = (date.ToUniversalTime() - epoch).TotalSeconds;

    if you need to convert your date from a string you can use DateTime.Parse and if you just want to work this out for the current time DateTime.Now will give you the date and time now

    Hi Kevin

    It seems like that's the way to do it :-) Now I'm having problems connecting the parsed date to the unix...

    string minDato = item.UpdateDate.ToString("yyyy, MM, dd");
string dateInput = @minDato;
DateTime parsedDate = DateTime.Parse(dateInput);

var date = new DateTime(parsedDate);
var offset = new DateTimeOffset(date);
var unixTime = offset.ToUnixTimeSeconds();

    It stops working at line "var date = new..." – and I've tried both "parsedDate", @parsedDate, "@ParcedDate"...?

    Yes I'm a newbee :-)

    Hi

    I am not sure you have to parse the date you actually have.

    have you tried just putting the date you have in the UpdateDate variable into the DateTimeOffset value ?

    var offset = new DateTimeOffset(item.UpdateDate)

    but just to be sure, try the pre .net4.6 version - just to be sure you aren't hitting an error because of your .net version so try : 

    var epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
var unixDateTime = (item.UpdateDate.ToUniversalTime() - epoch).TotalSeconds;
