Some LMT (local mean time) values in the tz database seem to be incorrect.
Below are the values I believe to be correct.

Alaska    America/Juneau    -8:57:41
Alaska    America/Yakutat    -9:14:55
Alaska    America/Anchorage    -9:59:36
Alaska    America/Nome    -11:01:38
Alaska    America/Adak    -11:46:38
Philippines    Asia/Manila    8:04:00
Guam    Pacific/Guam    9:39:00
Northern Mariana Islands    Pacific/Saipan    9:43:00
Samoa    Pacific/Apia    -11:26:56
American Samoa    Pacific/Pago_Pago    -11:22:48

Note that West Samoa is no longer the correct name; it is Samoa.

No LMT information was given for:

BIOT    Indian/Chagos    4:49:40
Cocos Islands    Indian/Cocos    6:27:40

Several geographic locations for Antarctica bases are not present in the tz
Some time ago I looked the latitude/longitude up from various sources, some
more reliable than others.
Locations missing in the tz database are:

Comandante Ferraz, King George Island    62:05S 058:24E

The names of the Chilean bases are incomplete - titles are omitted:
Escudero, South Shetland Islands    62:11:57S 058:57:35W

Villa Las Estrellas is the little village built around the Frei base.

Great Wall, King George Island    62:13S 058:58W

McMurdo, Ross Island    77:50S 166:36E
Amundsen-Scott, South Pole    90:00S 000:00E

Since I didn't bother to mention the sources (too many), you might take this
information 'cum granum salis', but anyway, it might be of some use.
Has anyone better information?

I shall publish a new web page with a compilation of some tz database
information in due time.
Compiling all information resulted in the above notes.
