Among my accumulation of time zone abbreviations I find:

	 GMT +

ACDT     10:30  Australian Central Daylight
ACST      9:30  Australian Central Standard
CADT     10:30  Central Australian Daylight
CAST      9:30  Central Australian Standard
CST       9:30  North/South Australian Central Standard
HDT      -9:30  Hawaiian Daylight (until 1947)
HST     -10:00  Hawaiian Standard (-10:30 until 1947)
IDT       4:30  Iran Daylight
IST       3:30  Iran Standard
IST       5:30  Indian Standard
IT        3:30  Iran
JT        7:30  Java
MT        8:30  Moluccas (obsolete)
NDT      -2:30  Newfoundland Daylight
NFT      -3:30  Newfoundland
NST       8:30  North Sumatran (obsolete)
NST      -3:30  Newfoundland Standard
SADT     10:30  South Australian Daylight
SAST      9:30  South Australian Standard

I think there are at least 8 separate half-hour zones there, if that's
what you mean by oddball time zones.  I don't know about any zones with
three-quarter hour offsets, but would like to know what they are.
