tz :: QuasiQuoter

Quasiquoter for parsing a TZTime at compile-time in the format: yyyy-mm-dd hh:mm:ss[.sss] [±hh:mm] [time zone].

The offset is optional, except when the local time is ambiguous (i.e. when the clocks are set back around that time in that time zone).

The offset can also be expressed using military time zone abbreviations, and these time zones abbreviations as per RFC 822 section 5: "UTC", "UT", "GMT", "EST", "EDT", "CST", "CDT", "MST", "MDT", "PST", "PDT".

Note: the time zone's rules are loaded from the embedded database using fromIdentifier.
