For what it's worth, a letter dated 1943-11-01 from E.N. Chase, station superintendant for BOAC at Bahrain, said that Jiwani was 6 hours ahead of GMT then whereas Karachi was 6½ hours. See page 86 of "File 16/53 Enquiries Re: Calculation of Local Time", British Library: India Office Records and Private Papers, IOR/R/15/2/1564, in Qatar Digital Library <https://www.qdl.qa/archive/81055/vdc_100000000282.0x00012b>. No doubt Chase was referring to the time at Jiwani Airport, which was I believe operated by the Royal Air Force at the time. It is curious that Jiwani Airport would have disagreed with India but perhaps 6.5 hours was a half-hour too far.
