Gary, Thanks for the follow up. I checked QUTCOFFSET and , sure enough, it's set at the shipped value of +00:00 ie. GMT. However, before setting to +01:00 (BST) I'll check that it won't impact anyone else. The only downside to this is the biannual manual adjustment. I'm not sure but I suspect that the JVM time would adjust automatically and correctly after having set the timezone to "Europe/London" AND with QTIME always set to GMT. I also assume that the GMT/BST changeover dates are known for some years to come and held somewhere within the JVM? Ideally, I'd prefer this option (if correct) but this is not possible since other applications require QTIME to be adjusted between GMT and BST.

It's supposed to be set to the offset from GMT so in your case that would be +1. QTIME is supposed to be set to the local time and QUTCOFFSET to the current GMT offset. I think this could fix your problem. You'll need to remember to change QUTCOFFSET back to zero when you go off of Summer Time. Also, I'm not sure what else this will affect. The Work Management book says it's used for intersystem time reconciliation but I'm not sure who else your 400 is connected to. If you have a test box available, it might be worth fiddling with.
