Module timezone 

The host’s local IANA timezone, resolved dynamically, and the wall clock an RFC-3339 timestamp reads as in it. A generic OS-env probe shared by the usage scan’s day-bucketing, the SCHEDULES schedule formatter and the turn rows a view draws from a transcript.

Functions

local_clock

An RFC-3339 instant the CLI wrote, as the reader’s own wall clock: HH:MM:SS for today’s, the date too for anything older, because a turn read from a transcript can be weeks old and a bare time would read as today. None for a string that does not parse, so a malformed row draws no clock rather than a fabricated one.

millis_between

The milliseconds from one RFC-3339 instant the CLI wrote to another. None unless both parse and the second is not earlier than the first.

system_timezone

The OS-configured IANA timezone, read dynamically. Uses iana-time-zone (multithread-safe on Unix, unlike time::UtcOffset::current_local_offset, which errors in a threaded process). Falls back to UTC with a warn only when the zone can’t be resolved - the rare exception, so “today” tracks the user’s wall clock.
