PerfKit, (a.k.a PERFSVM) doesn't like to have the time changing while
it's running, either. It gets confused about when midnight occurs.

Be sure to account for some software that does not like the time

We shutdown the following until after the SET TIMEZONE command is
issued; you may other ones:
1. SMTP - be sure to stay logged on after shutting it down so TCPIP
doesn't AUTOLOG it back on.
2. VMBACKUP and VMSCHED
3. All our SQL servers.
In the Spring, we bring them all back up immediately.
In the Fall, we wait one hour until the time reaches the time we shut
them down and then bring them all back up.

This is the first time (in quite some time) that I've had a Daylight
Saving Time (Spring Forward). Last year we did a Fall Backward by
shutting the system down for one hour.
So, here are my questions:
1) VM time has to be done manually? Has anyone done this via VMUTIL
(for example?
2) Does anything need to be done to the z/VSEs (when springing forward)?
3) Will z/VSE pick up the time change when it's changed on VM?
4) Are there special conditions for 2 and 3 above (specifically SET
CLOCK/ZONE/ZONEDEF/ZONEBDY settings)
