Are we talking about the value returned by time(2) or are we talking about an arbitrary offset from time(2) used as the local timezone. the tzfile format permits for some very screwy timezone trickery.<br><br>Setting time(2) using the date(1) command works well as long as the guest OS is not configured to synch from an external clock. Note that most modern linuxes attempt to set their local clock from some external master at boot. Also note that guest OS "hardware" clocks are not dependable and time drift sets in quickly.<br>

<br>
Turns out I might need to occasionally run some software with the system<br>
date tweaked. Unfortunately, doing a web search for something like<br>
"running xen different date" turns up a whole lot of date-stamped<br>
articles, etc., that don't talk about how the system date in a VM<br>
interacts with the host system date.<br>
<br>
So, before I dive into downloading Xen, and setting up a domU, I'd like<br>
to know whether there's any hope for telling the OS that it's 2003.<br>
<br>
Anyone have any knowledge on this?<br>
<br>
Thanks,<br>
jed<br>
