clock change

Hi

We had a AIX box built last year but was set to the correct GMT time, but using DST time zone. In march this year the clocks went forward without issues. (if I remember a couple of weeks early due to the DST zone)

This year we decided to change the clock to the correct time zone before the clock change at the weekend.

Therefore the timezone was set to BST, however this weekend (28th October) the clock didnt change.

Now we dont really know AIX and have a third party do all the work. What we have been told is there is some file that needs changing and was missed when they set the clock to BST. But one of the questions is why didnt the clocks adjust automatically when set to DST on Sunday.

My next question is

We have now been told that to change the clock to BST correct time, we have to stop our applications/stop oracle and reboot the server so it will automatically change when the clocks jump forward/backwards.
