(To differentiate among ambiguous time zone abbreviations, I'm using NAEST for North American Eastern Standard Time, AuEST for Australian Eastern Standard Time and BrST for British Summer Time.)
6 AM BrST = midnight NAEST = 3 PM AuEST
6 AM GMT = 1 AM NAEST = 4 PM AuEST
European parts of the U. K. observe Summer Time from the last Sun. of March until the last Sun. of Oct.

With the exception of Panama (which is located on GMT-5, or EST) most of Central America is located within the GMT-6 (or CST) time zone.
India is in the IST time zone, which does not observe daylight savings, (GMT +5.30) putting it 10 hours and 30 minutes ahead of the EST time zone which does observe daylight savings. Therefore, 8am in EST is 7.30pm in IST outside daylight savings and 6.30pm during.
Eastern Standard Time (EST) is one hour ahead of Central Standard Time (CST). So at 11:30 am in EST zone it would be 10:30 am in CST zone. EST = GMT -5 CST = GMT -6
London is 6 hours ahead of Central Time. So, 7 PM Central Time is 1 AM Greenwich Mean Time (the time zone that London is in).
