Sorry for the lateness of this response. Guests clocks can't drift from the VM clock, as their TOD is computed by applying a fixed offset, if any, to the VM TOD. The only way to change a guest's TOD is via SET CLOCK instruction or the SET VTOD command. As the VM TOD drifts, so do the TODs of all the guests, all at the same rate. I suppose we could have introduced the concept of "virtual clock drift" and allow you to configure the rate of drift, just for fun. :-) Alan Altmark Sr. Software Engineer IBM z/VM Development ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
