Does daylight saving time affect EST to GMT conversion?
Yes. EST switches to EDT (UTC-4) in summer and GMT switches to BST (UTC+1) in summer, so the gap between the two zones changes during DST periods. The live clocks on this page use the IANA timezone database and always reflect the correct current offset automatically.
