C#: Get unix timestamp with microseconds-CodePudding

How can I get the current unix timestamp in microseconds in .NET 5? I have looked around and only found a way to get it in milliseconds with ToUnixTimeMilliseconds, and nothing that would include microseconds.

CodePudding user response：

You just need to subtract the Unix epoch (1970-01-01T00:00:00Z) from the DateTimeOffset to get a TimeSpan, then get the microseconds from that by dividing the total number of ticks by 10:

using System;

public static class DateTimeOffsetExtensions
{
    private static readonly DateTimeOffset UnixEpoch =
        new DateTimeOffset(1970, 1, 1, 0, 0, 0, TimeSpan.Zero);

    public static long ToUnixTimeMicroseconds(this DateTimeOffset timestamp)
    {
        TimeSpan duration = timestamp - UnixEpoch;
        // There are 10 ticks per microsecond.
        return duration.Ticks / 10;
    }
}

public class Test
{
    static void Main()
    {
        DateTimeOffset now = DateTimeOffset.UtcNow;
        Console.WriteLine(now.ToUnixTimeMicroseconds());
    }
}
