This is something brand new for me since I have never supported a server where the users were in another timezone. Thanks
Solved! Go to Solution.

SolutionTime handling on OpenVMS isn't well enough abstracted to support multiple time zones in a cluster. All nodes, and therefore all users must be in the same zone, and be synchronized.
Simple example, time stamps on objects are stored in local time. This is an architectural limitation. To support multiple time zones, the stamps should be stored in UTC, but displayed according to a zone, which could be defined at system, group, user or process level. Unfortunately it's not possible to change the architecture without breaking lots of things (back when OpenVMS was being designed, the idea of a system being "large enough" to span timezones wasn't really on the horizon).
That said, there are time zone routines which allow an application to manipulate times in other zones (but it requires translating input times and timestamps into UTC using the system timezone, then translate to the target zone, very ugly!).
Depending on your requirements, you could define your own process time zone, code applications to honour it, and maybe modify a few system commands (like SHOW TIME).
Back in 1999 there were a number of software offerings that claimed to be able to shift time on a per process basis (target market was Y2K testing). Some worked reasonably well, others didn't. No matter how they did it, there were always examples of code for which it wouldn't work correctly.
Some customers with clusters that cross timezone boundaries run their systems in UTC, and expect their users to just live with it.

But as John said, their are some potential problems. E.g. show queue to a file and parse that file will not give the local time.
