class Time::TZLocation

Overview

A time location capable of computing recurring time zone transitions in the future using POSIX TZ strings, as defined in POSIX.1-2024 Section 8.3, or in IETF RFC 9636.

These locations are returned by Time::Location.posix_tz.

Defined in:

time/tz.cr

Instance Method Detail

def ==(other : self) #
Description copied from class Time::Location

Returns true if other is equal to self.

Two Location instances are considered equal if they have the same name, offset zones and transition rules.


def hash(hasher) #
Description copied from class Time::Location

Returns true if other is equal to self.

Two Location instances are considered equal if they have the same name, offset zones and transition rules.
