Try this:

dtLCL = datetime('now', 'TimeZone','local')                 % Current Local Time
dtUTC = datetime(dtLCL, 'TimeZone','Z')                     % Current UTC Time

That will give you both the local time and the corresponding UTC time.

This gives you a simple network time, which does not rely on local computer time:

url_time = webread('http://worldtimeapi.org/api/timezone/Etc/UTC')

This just converts your local computer time to UTC. So if your local computer time is incorrect for any reason, the utc_time will be also incorrect.
