MK Scarlett said:I've got it: IST, means:
http://www.timeanddate.com/time/zones/istIndia Standard Time (IST) is 5:30 hours ahead of Coordinated Universal Time (UTC). This time zone is a standard time zone and is used in: Asia. India Standard Time is a half-hour time zone. Its local time differs by 30 minutes from the usual one-hour time zone interval.
This time zone is often called Indian Time.
I cannot do the maths right now as it is late here, but I will give a try on tomorrow if not already done by someone else.
Comparing the UTC times from RSOE EDIS _http://hisz.rsoe.hu/alertmap/index2.php?lang with the ones on the map, it looks like the latter are actually Iranian Standard Time (UTC+0330) rather than Indian. To convert the UTC times to Iranian Time you basically add 3:30 hours. Still, both the Afghanistan and Indonesia earthquakes on the map would be off by 1 hour.
Afghanistan (4.6) - May 12 2015
UTC: 09:15 AM --> IST: 12:45 PM
Indonesian Archipelago (5.4) - May 12 2015
UTC: 09:22 AM --> IST: 12:52 PM
Nepal (7.4) - May 12 2015
UTC: 09:05 AM --> IST: 12:35 PM
The fact that they all occurred within 17 minutes of each other is still very interesting.
