Understanding the Time Zones
- PST (Pacific Standard Time): UTC-8, used Nov–Mar
- PDT (Pacific Daylight Time): UTC-7, used Mar–Nov
- GMT (Greenwich Mean Time): UTC+0, used Oct–Mar

DST Mismatch Periods
The US and UK change clocks on different dates, creating brief periods where the gap is 7 hours instead of 8. This happens twice a year for about 2-3 weeks.
