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.
