GTM 3 l quess or GTM -3
Nepal? The only time zones that are off like that are Nepal, Australia and New Zealand.
Each Time Zone is 15 Degrees of Longitude Wide.
1:15 PM is actually 1315 and 4 AM is actually 0400 Subtract to find the difference.
1315 - 0400 is 9:15 So that is 9 time zones ea
Chicago is in time zone GMT-5 and 9 time Zones east would be GMT + 4
The Central Longitude Line for GMT+4 is 60 Degrees East
Time Zone (local) of Chicago approximates to -6 hrs from UT, that is 90ºW. Now,
1:15 P.M. - 4 AM = 1:15 hrs - (- 4hrs) = 6:15 hrs. = 6¼ hrs
@ 15º / hr, this translates to
6¼ X 15º = 93¾º positive (Eastward) from 90ºW (because Chicago follows this meridian)
93¾º E - 90º W = 3¾º E = 3º 45' E.
The meridian passes through Iberia (Spain/Portugal)& West Africa [I haven't checked up maps; please do]
