Action adding record to google calendar - result adds 1hr to calendar time

[gpadmin]

I have an action adding an event row to google calendar from booking including startdatetime and enddatetime. It works until it get's to March then entries add 1 hr to the calendar record. I read something about the daylight savings issue in google calendar? how do I fix this in the app? I'm in california timezone. I'm at a standstill until this is resolved. 

Please advise.

Thank you
