HI,
So the alarm times are set on the robot where the alarm was generated.
The alarms times are not touched when transferred to the robot to the hub or between hubs.
Having hubs in different time zones should not affect anything in the system many clients have this setup.
We do expect that the primary UIM, UMP and SQL server server all be on the same time zones or you might see some odd times.
The actual time regardless of time zone should be synced to an internet time source to keep all systems in sync but setting the local time zone for the area the machine is in or servicing should not affect anything else.
I hope I answered your question.
