C# / .NET - create date and time from milliseconds
12 points
In C# / .NET it is possible to get DateTime instance from total milliseconds in few ways.
xxxxxxxxxx1
public static class TimeUtils2
{3
public static DateTime GetDateTime(long milliseconds, 4
DateTimeKind kind = DateTimeKind.Utc)5
{6
long ticks = milliseconds * TimeSpan.TicksPerMillisecond;7
8
return new DateTime(ticks, kind );9
}10
}Example:
xxxxxxxxxx1
Console.WriteLine(TimeUtils.GetDateTime(0));2
Console.WriteLine(TimeUtils.GetDateTime(63701329632387));Output:
xxxxxxxxxx1
01/01/0001 00:00:002
08/13/2019 21:47:12Note: time is measured since 01-01-0001 00:00:00.000.
