Best overlap: 8:00 AM to 10:00 AM in San Francisco is 4:00 PM to 6:00 PM in Reykjavik.
Schedule calls for 8:00 AM to 10:00 AM in San Francisco — your colleagues in Reykjavik will be online from 4:00 PM to 6:00 PM. Reykjavik is 8 hours ahead of San Francisco, so you only get about 2 hours of overlap a day — worth locking in a standing time like 8:00 AM in San Francisco (4:00 PM in Reykjavik) before it slips. These times hold for most of the year, but San Francisco's daylight saving (which Reykjavik doesn't use) shifts them by an hour twice annually.
