Q What is the best time for a conference call between UTC and GMT?

The optimal meeting window is **9:00 AM – 5:00 PM UTC = 9:00 AM – 5:00 PM GMT (100% identical continuous sync)**. This ensures participants in both Global Reference Coordinate and United Kingdom, Ireland & Western Europe are awake and within active business hours.
