GMTOffsetFromTz: Determine Time Offset From Timezone

Description

The data are from https://www.timeanddate.com/time/zones/ and were hand-edited to develop this code, so there may be errors. Also, note that some of these contradict; if you examine the code, you'll see some commented-out portions that represent solving conflicting definitions by choosing the more common timezone abbreviation over a the less common one.

Usage

GMTOffsetFromTz(tz)

Value

Number of hours in offset, e.g. AST yields 4.

Arguments

tz

a timezone, e.g. UTC.
