QuickFIX - set StartTime\EndTime - quickfix

Question

QuickFIX has a configuration file where you set StartTime and EndTime. Unfortunately AFAIK QuickFIX only supports UTC for this configuration, whereas exchanges are often timezone dependent. This means that you need to remember to update this configuration file every time the clock changes.
Is there a way to set the StartTime \ EndTime parameters programatically instead of through the configuration file? That way you could adjust the timeset the correct values programatically.

Answer 1

There is a way to set this. You can can set a timezone as follows:
TimeZone=America/New_York
see the configuration guide.
It is weird that it is not in the quickfix configuration guide and it is present in the quickfixJ guide.

Answer 2

in our production environment we use always UTC times.
In the QuickFIX config file add for every counterparty the following line:
UseLocalTime=N
Please read the documentation here:
http://www.quickfixengine.org/quickfix/doc/html/configuration.html#Session

Answer 3

as per quickfix docs you should add
set UseLocalTime=Y
Indicates StartTime and EndTime are expressed in localtime instead of
UTC. Times in messages will still be set to UTC as this is required by
the FIX specifications.

Answer 4

We had an error
System.ArgumentException: Only UTC time is supported
Parameter name: oldtime
at QuickFix.SessionSchedule.IsNewSession(DateTime oldtime_utc, DateTime testtime_utc)
at QuickFix.Session.get_IsNewSession()
and the only way to fix it was to delete the store directory. Presumably the session timestamp like this
