Xen users - Dec 2012 - xen xl command set date for hvm

Hi,
New to this list and kindof new to Xen.
I''m testing some code that works with communications between different
Windows hosts.
Right now I''m using Xen and a dozen or so hvms.

It would be convenient if I could set the date/time of each hvm when I
launch them with XL.
Is there a way to do this?

The code I''m working with has a lot of logic that hinges on each
host''s
date/time.
So to test this to the degree I''d like - I need an automated way to
change
each hvms date/time and launch them.

Thanks a lot! :)

Toni

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.
