You can add an offset to the emulated RTC time using the rtc_timeoffset
option, which is documented in the xl.cfg(5) man page. It's not quite
setting the date and time but if you know the current time you can come
close.

Most OSes initialise their wallclock time based on the RTC.

You'd want to avoid any sort of network time sync though e.g. NTP or the
Windows equivalent. (does Active Directory do time synchronisation?)
since that might undo the offset.
