30 paź 2008 · To convert it back from DateTime to Unix millisecond time: DateTimeOffset backToUnixTimeOffset = new DateTimeOffset(dt, TimeSpan.Zero); long backToMillisecs = backToUnixTimeOffset.ToUnixTimeMilliseconds();
10 kwi 2016 · Essentially, these are two methods to convert DateTime objects to and from the Unix epoch time (two methods for each action). There is a non-nullable, and a nullable version for each conversion.
The following example calls the ToUnixTimeSeconds method to return the Unix time of values that are equal to, shortly before, and shortly after 1970-01-01T00:00:00Z. public class Example. public static void Main() DateTimeOffset dto = new DateTimeOffset(1970, 1, 1, 0, 0, 0, TimeSpan.Zero);
12 lut 2024 · This method offers a straightforward and efficient way to calculate the elapsed time between a specific date and time and the Unix epoch. Let’s explore a complete example demonstrating how to obtain the Unix timestamp in C# using TimeSpan and the TotalSeconds method.
Source: DateTime.cs. The value of this constant is equivalent to 00:00:00.0000000 UTC, January 1, 1970, in the Gregorian calendar. UnixEpoch defines the point in time when Unix time is equal to 0. C#.
Convert date to epoch or unix timestamp in C#. We can convert human readable date to timestamp using ToUnixTimeMilliseconds() method. var dateTime = new DateTime(2021, 02, 21, 22, 0, 0, DateTimeKind.Utc); var dateWithOffset = new DateTimeOffset(dateTime).ToUniversalTime(); long timestamp = dateWithOffset.ToUnixTimeMilliseconds(); More about ...
