ANNA time zone location code

TZLC - no UN LOCODE

Temporarily assigned codes start with "0" and do not overlap with a code that starts with O and has the same characters in the other positions.

tzid	ANNA tzlc
Europe/Busingen	0BS
America/Danmarkshavn	0DN
Asia/Hebron	0HB
America/Santa_Isabel	0IS
Asia/Jerusalem	0JE
Asia/Khandyga	0KH
America/Shiprock	0SH
Asia/Ust-Nera	0UN
America/Indiana/Vevay	0VV

TZLC - ending in T

15 UN/LOCODE end in "T" and could be mistaken for a time if only the location part is seen.
