Daylight Savings Time

Since Daylight savings time my VMS time is an hour behind. The time in Cache is fine. But if I change the time in VMS, the Cache time moves ahead as well. Does anyone know how I may change this without changing my Cache time?

Re: Daylight Savings Time

More info is required...

Which VMS version?

Is Cache Intersystems Cache database (which is written in C and uses the C-RTL routines to fetch/display time)?

Please post the output of

$ show logical/system sys$*time*

Do you use NTP or DTSS to synch time on this system?

How do you handle daylight savings time changes?

Re: Daylight Savings Time


about correctly setting the various logicals.

In some versions of VMS you had to change the local time offset in UCX as this was the one that the C run time library used.
