Daylight savings and google calander

I just got a reminder about my kid's dentist appointment that I made in February. I went into google calendar to make sure it was there, it was there but the time was wrong because of Daylight savings. Since the event was added in February Google Calendar put it as GMT-5 and now were are GMT-4.

I've already missed 4 things because of this (I've started putting the time in the event description) and I'm hoping someone has found a way to avoid this hour change.
