FM Times Getting 3 Hrs Added in iCal

I have a solution working with Zulu that has developed a "time warp" where an entry like 1:00 PM in the time field for an event in the FM database appears as 4:00 PM in iCal. Dates are fine. Just the time of the event is off by 3 hrs.
Just started happening after we shifted our clocks back an hour here in Ohio. Is there a "time zone" setting in the Filemaker code being employed by Zulu that I need to adjust?
Thanks if anyone has any insights on this.
