Console.WriteLine(DateTimeOffset.UtcNow.ToUnixTimeSeconds());

Timestamp to date

using System;

Console.WriteLine(DateTimeOffset.FromUnixTimeSeconds(1_700_000_000).ToString("O"));

Date to timestamp

using System;

Console.WriteLine(DateTimeOffset.Parse("2023-11-14T22:13:20Z").ToUnixTimeSeconds());

How to use it

Copy the current-time example into your C# environment to read Unix seconds.
Run the second example to display 1700000000 as a UTC date.
Run the last example to convert that date back into seconds.

DateTimeOffset represents a time together with its UTC offset. The O format preserves that offset. Use the UnixTimeMilliseconds methods when the source sends milliseconds.
