Daylight Savings Time

Prendi — Wed, 17 May 2006 09:29:04 GMT

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?

Thanks

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?

See
http://h71000.www7.hp.com/faq/vmsfaq_005.html#time4

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.
