Christopher,
There are no standards for the three letter time zones. AST is Alaska
Standard Time and Atlantic Standard Time. MST is Moscow Summer Time. It is
also Phoenix which has no daylight savings time as well as Mountain Standard
time.
I build a table of explicit time zones to 3 or 4 letter codes and had lots
of duplicates. It was to build a TZ= string. As you might note functions
using the TZ= string ignore these codes when calculation time zone offsets
or daylight time because they are useless.
I use the data from ICU which comes from the Olson source at
ftp://elsie.nci.nih.gov/pub/ Get the tzdata..... file.
