I got the same problem, after updating new DST patches from MSFT several times. Guess I ccould manually change time on PC, but the thing is, no matter what I do, Tradestation chart now shows central time trading session (i.e., open at 8:30 and close at 3:00).
Do I have to change trade sessions manually in TS? Thought after updating for DST, TS would take care of itself, no?
Any suggestions will be appreciated.

We have quite a number of testing computers here and we are well aware of the DST potential issues. I have gone all the way to blog the possible issues on our site.
But, as of this morning, we have 7 computers that their clocks simply do not switch properly. They are all updated the same way by our admin staff.
Think about software that depends on specific US time stamps - and that those servers behind are not handling the date time correctly ...
The mess will last for couple of weeks so be prepared.
The sarcastic thing is - US government is going to study if this change of DST will be benefitial.
It would be very funny if they simply dump this new DST schedule by next year.![]()
