How do I convert UTC time to Unix time?

I have a datafile with time in UTC, for example: 192503.000 where the format is hhmmss.ss format, where hh is hours (00–23), mm is minutes, and ss.ss is seconds and fractions of seconds.. How do I convert this to Unix time?

You are going to need a date (y,m,d) to go with that to calculate Unix Time.

%Example
y = datetime('now','TimeZone','UTC')

y = datetime
   19-Sep-2023 16:47:22

%Get time in UNIX format
z=posixtime(y)

z = 1.6951e+09

%Change the display format
format longg
z

z = 
          1695142042.43009

If you have data in any other format then datetime(), convert it to datetime() and the use posixtime
