How to get Unix timestamp in C#

Unix timestamps are mainly used in Unix operating systems. But it helps everyone operating system as it represents time in all time zones.

Unix timestamp represents time in seconds. The Unix epoch begins on the 1st January 1970.

Thus, a Unix timestamp is the number of seconds between a specific date

Example

Use DateTime.Now.Subtract to get the Unix timestamp().Total seconds Method

class Program{
   static void Main(string[] args){
      Int32 unixTimestamp = (Int32)(DateTime.Now.Subtract(new
      DateTime(1970, 1, 1))).TotalSeconds;
      Console.WriteLine("The Unix Timestamp is {0}", unixTimestamp);
      Console.ReadLine();
   }
}

Output

1596837896

Example

to get the Unix Timestamp Using DateTimeOffset.Now.ToUnixTimeSeconds() Method

class Program{
   static void Main(string[] args){
      var unixTimestamp = DateTimeOffset.Now.ToUnixTimeSeconds();
      Console.WriteLine("The Unix Timestamp is {0}.", unixTimestamp);
      Console.ReadLine();
   }
}

Output

1596819230.

Example

Use TimeSpan structure method to obtain Unix timestamp

class Program{
   static void Main(string[] args){
      TimeSpan epochTicks = new TimeSpan(new DateTime(1970, 1, 1).Ticks);
      TimeSpan unixTicks = new TimeSpan(DateTime.Now.Ticks) - epochTicks;
      Int32 unixTimestamp = (Int32)unixTicks.TotalSeconds;
      Console.WriteLine("The Unix Timestamp is {0}.", unixTimestamp);
      Console.ReadLine();
   }
}

Output

1596839083
