What is the local sun time in Charleston, South Carolina, (77 degrees W), when it is 4 AM EST in Charleston?

Question

How do I find the difference between sun time and normal time in Charleston?

Answer 1

77 degrees west is 5 hours and 8 minutes if you allow 15 minutes per degree (24 hours is 360 degrees).

So your local time is 5 hours and 8 minutes behind Universal Time (UTC). But your standard time (EST) is 5 hours behind UTC. So you local time is 8 minutes behind standard time, and the time is 3:52 am.
