Module tm

Expand description

Git-compatible time conversion helpers (ported from Git’s date.c).

Constants§

atoi_bytes: C atoi on a byte slice (optional leading sign for digits).
date_overflows
empty_tm
get_time_sec: Read GIT_TEST_DATE_NOW if set, else current time (seconds).
gm_time_t: Apply Git’s tz HHMM encoding to a UTC instant so gmtime_r yields wall-clock digits.
init_tm_unknown
is_date_known
local_time_tzoffset^⚠: Git’s local_time_tzoffset — offset for t in the local zone, as HHMM encoding.
local_tzoffset: Git’s local_tzoffset for a UTC instant.
match_string
maybeiso8601
nodate
parse_timestamp_prefix: Parse leading digits as base-10 (strtoumax / Git’s parse_timestamp).
skip_alpha
time_to_tm^⚠: time_to_tm — UTC tm for display with explicit tz offset metadata.
time_to_tm_local^⚠: time_to_tm_local — localtime_r for the current TZ environment.
tm_to_time_t: Git’s tm_to_time_t — like mktime, but without normalization of tm_wday / tm_yday.

Timestamp: Unix timestamp as used by Git (timestamp_t is typically uintmax_t).
TzHhmm: Timezone in Git’s signed HHMM encoding (e.g. +200 for +02:00, -500 for -05:00).
