DateTime-Lite-v0.4.0

Changes for version v0.4.0 - 2026-04-14

  • Fixed t/12.tz_database.t on Windows (Strawberry Perl): replaced POSIX::mktime with Time::Local::timegm for pre-1970 timestamps, which POSIX::mktime cannot handle on Windows.
  • Added start_of( $unit ) mutator, which modifies the datetime object in place to the first instant of the given unit. Supported units are second, minute, hour, day, week, local_week, month, quarter, year, decade, and century. Delegates to truncate() for most units; decade and century are handled independently. Returns the modified object on success.
  • Added end_of( $unit ) mutator: modifies the datetime object in place to the last nanosecond of the given unit (i.e. the nanosecond before the start of the next unit). Supports the same units as start_of(). Handles variable-length units such as months and leap years correctly without hardcoding boundary values. Returns the modified object on success.
  • Added test suite t/15.start_end_of.t covering all supported units for both start_of() and end_of(), including edge cases such as February in leap and non-leap years, quarter boundaries, decade and century boundaries, timezone and locale preservation, and invalid unit handling.
  • Added POD documentation for posix_tz_lookup() under a new =head1 LOW-LEVEL XS UTILITIES section in DateTime::Lite, documenting the XS function signature, all supported POSIX TZ string rule forms (Jn, n, Mm.w.d), the RFC 9636 extensions for TZif v3+, and the structure of the returned hashref.
