Time Zone Hell

[dbasnett]

in another forum i was going to help someone with a problem converting between timezones. to make a long story short, TimeZoneInfo.GetSystemTimeZones() returns a list of 90, without abbreviations. Just so happened that the one I was looking for wasn't there, it was old. i found it eventually.

so far my list of timezones is about 300, with GMT offsets. here is a sample.


COT Colombia Time (GMT-05:00)
CS Central Summer Time Australia (GMT+10:30)
CST Central Standard Time Australia (GMT+9:30)
CST Central Standard Time North America (GMT-06:00)
CST Central Summer Time Australia (GMT+10:30)
CST China Standard Time (GMT+08:00)
CVT Cape Verde Time (GMT-01:00)
CXT Christmas Island Time Australia (GMT+07:00)
D Delta Time Zone Military (GMT+04:00)
DAVT Davis Time (GMT+07:00)
DTAT District de Terre Adélie Time (GMT+10:00)

SBT Solomon Island Time (GMT+11:00)
SCDT Santa Claus Delivery Time (GMT+13:00)
SCST Santa Claus Standard Time (GMT+12:00)
SCT Seychelles Time (GMT+04:00)
SGT Singapore Time (GMT+08:00)
SIT Spratly Islands Time (GMT+08:00)
SLT Sierra Leone Time (GMT+00:00)
SRT Suriname Time (GMT-03:00)
SST Samoa Standard Time (GMT-11:00)
SST Swedish Summer Time Europe (GMT+02:00)
SWT Swedish Winter Time Europe (GMT+01:00)
SYST Syrian Summer Time (GMT+03:00)
SYT Syrian Standard Time (GMT+02:00)


as you can see there are duplicate abbreviations.
