Expand description

Parse a timezone from s and return the offset in seconds.

The consume_colon function is used to parse a mandatory or optional : separator between hours offset and minutes offset.

The allow_missing_minutes flag allows the timezone minutes offset to be missing from s.

The allow_tz_minus_sign flag allows the timezone offset negative character to also be − MINUS SIGN (U+2212) in addition to the typical ASCII-compatible - HYPHEN-MINUS (U+2D). This is part of RFC 3339 & ISO 8601.
