Have had all different environments blow up with time change in the past. Now, we build all systems in UTC and allow TZ redirection. Haven't had an issue since

Interesting, ty

That applied to nonP only... But included pvs and MCS images

Nothing here

@Hal Lange Did you ever find out WHY this happened?

samesy, always saw it more with PVS, and also app layering...not so much with MCS. Usually recmmend new builds on Sunday, or if your doing manual pvs, new versions.

why... it seemed to be the changing of the time by that hour (especially in Fall), seemed to cause issues. Our best guess was when the time jumped to before the system logged it booted. if we let them sit for an hour or 2 they seemed to calm down, but being a 24x7 shop makes it very difficult to let a system site idle for that long. the problem was never as prolific in the spring time change. to avoid the pain of redoing an image on a sunday after the time change... we just moved to UTC about 3 or 4 years ago and have never had the issue since.

same observation. Fall is always worse

Yep - but only at one customer... MCS machines didn't auto-update time when daylight savings rolled over, I had to fire up the master, manually update the time on it and push the image out again to resolve it.

PVS, yeah pretty regularly. MCS, not so much. Moving to UTC across the env currently so hopefully that will be the last of it.

Thanks guys
