TimeWindows for Summer/Winter Pacific Time

Hi Everyone,

CPS build M33.104.

We have two jobs, one for PST and another for PDT and are mutually exclusive.

The days on which the Day light savings switch happens is not constant, it changes from year to year.

2015 - Mar 8 - Nov 1

2014 - Mar 9 - Nov 2

How do i create a time window that is open only for summer and another, only for winter.

thanks

Nanda
