Time-zone abbreviations were never standardised: several countries independently picked the same letters. IST is one of the worst offenders, with 3 meanings in current use. This is why calendar software and databases use IANA identifiers like Asia/Kolkata instead: they are unique, and they carry the daylight-saving rules with them.
