Class: TZInfo::TimezoneTransition
- Defined in:
- lib/rubypitaya/app-template/vendor/bundle/ruby/3.1.0/gems/tzinfo-2.0.5/lib/tzinfo/timezone_transition.rb
Overview
Represents a transition from one observed UTC offset (TimezoneOffset to another for a time zone.
Instance Attribute Summary collapse
-
#offset ⇒ TimezoneOffset
readonly
The offset this transition changes to.
-
#previous_offset ⇒ TimezoneOffset
readonly
The offset this transition changes from.
-
#timestamp_value ⇒ Integer
readonly
When this transition occurs as an ‘Integer` number of seconds since 1970-01-01 00:00:00 UTC ignoring leap seconds (i.e. each day is treated as if it were 86,400 seconds long).
Instance Method Summary collapse
-
#==(tti) ⇒ Boolean
(also: #eql?)
Determines if this TimezoneTransition is equal to another instance.
-
#at ⇒ Timestamp
Returns a Timestamp instance representing the UTC time when this transition occurs.
-
#hash ⇒ Integer
A hash based on #offset, #previous_offset and #timestamp_value.
-
#initialize(offset, previous_offset, timestamp_value) ⇒ TimezoneTransition
constructor
Initializes a new TimezoneTransition.
-
#local_end_at ⇒ TimestampWithOffset
Returns a TimestampWithOffset instance representing the local time when this transition causes the previous observance to end (calculated from #at using #previous_offset).
-
#local_start_at ⇒ TimestampWithOffset
Returns a TimestampWithOffset instance representing the local time when this transition causes the next observance to start (calculated from #at using #offset).
Constructor Details
#initialize(offset, previous_offset, timestamp_value) ⇒ TimezoneTransition
Initializes a new TZInfo::TimezoneTransition.
TZInfo::TimezoneTransition instances should not normally be constructed manually.

#timestamp_value ⇒ Integer (readonly)
When this transition occurs as an ‘Integer` number of seconds since 1970-01-01 00:00:00 UTC ignoring leap seconds (i.e. each day is treated as if it were 86,400 seconds long). Equivalent to the result of calling the value method on the TZInfo::Timestamp returned by #at.

#==(tti) ⇒ Boolean Also known as: eql?
Determines if this TZInfo::TimezoneTransition is equal to another instance.

#at ⇒ Timestamp
Returns a TZInfo::Timestamp instance representing the UTC time when this transition occurs.
To obtain the result as a ‘Time` or `DateTime`, call either to_time or to_datetime on the TZInfo::Timestamp instance that is returned.

To obtain the result as a ‘Time` or `DateTime`, call either to_time or to_datetime on the TZInfo::TimestampWithOffset instance that is returned.
