What date format is 636529536000000000?

I have to maintain an ASPX page that increments the date/time by passing a value in the querystring in this format:

636529536000000000 in reference to 31 January 2018

636530400000000000 in reference to 01 February 2018

The url format is: /reservas.aspx?t=636530400000000000

What is this date/time format?

Solution

  • It is the number of ticks where a tick is one hundred nanoseconds or one ten-millionth of a second. The number of ticks is measured since the epoch DateTime.MinValue (12:00:00 midnight, January 1, 0001). For example:

    new DateTime(636529536000000000).ToString("F", CultureInfo.InvariantCulture)

    outputs:

    Wednesday, 31 January 2018 00:00:00
