Quick answer
5 PM PST is 1 AM GMT in London. The 8-hour gap between Pacific Standard Time and the UK is maintained year-round because both zones observe daylight saving. End of Pacific day is deep into the UK night.
5 PM PST in London: what to know
5 PM on the US West Coast 鈥?the end of the standard Pacific working day 鈥?corresponds to 1 AM in London. The UK business day ended eight hours earlier. This is the widest practical gap in the US-UK scheduling challenge. All London-facing deliverables, updates, and handoffs from the Pacific working day should be sent by 9 AM Pacific at the latest to reach London during their working hours. After 9 AM Pacific, all US-London communication must be asynchronous.
For one-time meetings, write both local times in the invite. For recurring meetings, check daylight saving transitions in late March and late October. Use the Meeting Time Finder to compare more cities.
