There is a one hour difference for each 15 degrees of longitude, thus 45 degrees west of California is 3 hours earlier than the time in California. Example: 8 PM in Cal = 5 PM "out there" 45 degrees west.
There is no city at exactly 77 degrees north latitude and 45 degrees west longitude as this location is in the Arctic Ocean, north of mainland Europe.
The latitude and longitude for 46 degrees North latitude from the Prime Meridian are approximately 46 degrees North latitude, 0 degrees longitude. Moving to 21 degrees South, 35 degrees West would take you to approximately 21 degrees South latitude, 35 degrees West longitude. Continuing to 20 degrees South, 45 degrees West would position you at approximately 20 degrees South latitude, 45 degrees West longitude. Finally, moving to 20 degrees North would bring you around 20 degrees North latitude, along the same longitude as the previous location (45 degrees West).
If it is 10 am at 45 degrees W longitude, it is 4 pm at 45 E longitude.
That point is located in the North Atlantic Ocean.
