They're using GPS rather tnan UTC time.  Presumably some SCPI like this:

:DIAG:GPS:UTC?

will check and this:

:DIAG:GPS:UTC 1

will change it.  You may have to reset/reboot the units after changing time
scale.  Check the manual.

Don't have any insight into this.  Perhaps you're triggering on the wrong
edge plus an offset.  After due diligence (there's a lot of information
about the Z38xx to read) you could ask on time-nuts.
