• Object
• TimezoneInfo
• DataTimezoneInfo
• TZInfo::DataSources::ConstantOffsetDataTimezoneInfo

Defined in:

lib/tzinfo/data_sources/constant_offset_data_timezone_info.rb

Overview

Represents a data time zone defined by a constantly observed offset.

Instance Attribute Summary

• #constant_offset ⇒ TimezoneOffset readonly

  The offset that is constantly observed.

Attributes inherited from TimezoneInfo

#identifier

Instance Method Summary

• #initialize(identifier, constant_offset) ⇒ ConstantOffsetDataTimezoneInfo constructor

  Initializes a new ConstantOffsetDataTimezoneInfo.

• #period_for(timestamp) ⇒ TimezonePeriod

  An unbounded TimezonePeriod for the time zone's constantly observed offset.

• #periods_for_local(local_timestamp) ⇒ Array<TimezonePeriod>

  An Array containing a single unbounded TimezonePeriod for the time zone's constantly observed offset.

• #transitions_up_to(to_timestamp, from_timestamp = nil) ⇒ Array

  An empty Array, since there are no transitions in time zones that observe a constant offset.

Constructor Details

#initialize(identifier, constant_offset) ⇒ ConstantOffsetDataTimezoneInfo

Initializes a new TZInfo::DataSources::ConstantOffsetDataTimezoneInfo.

The passed in identifier instance will be frozen. A reference to the passed in TimezoneOffset will be retained.

Parameters:

• identifier (String) —

  the identifier of the time zone.

• constant_offset (TimezoneOffset) —

  the constantly observed offset.

Raises:

• (ArgumentError) —

  if identifier or constant_offset is nil.

# File 'lib/tzinfo/data_sources/constant_offset_data_timezone_info.rb', line 19

def initialize(identifier, constant_offset)
  super(identifier)
  raise ArgumentError, 'constant_offset must be specified' unless constant_offset
  @constant_offset = constant_offset
end

Instance Attribute Details

#constant_offset ⇒ TimezoneOffset (readonly)

Returns the offset that is constantly observed.

Returns:

• (TimezoneOffset) —

  the offset that is constantly observed.

# File 'lib/tzinfo/data_sources/constant_offset_data_timezone_info.rb', line 9

def constant_offset
  @constant_offset
end

Instance Method Details

#period_for(timestamp) ⇒ TimezonePeriod

Returns an unbounded TimezonePeriod for the time zone's constantly observed offset.

Parameters:

• timestamp (Timestamp) —

  ignored.

Returns:

• (TimezonePeriod) —

  an unbounded TimezonePeriod for the time zone's constantly observed offset.

# File 'lib/tzinfo/data_sources/constant_offset_data_timezone_info.rb', line 28

def period_for(timestamp)
  constant_period
end

#periods_for_local(local_timestamp) ⇒ Array<TimezonePeriod>

Returns an Array containing a single unbounded TimezonePeriod for the time zone's constantly observed offset.

Parameters:

• local_timestamp (Timestamp) —

  ignored.

Returns:

• (Array<TimezonePeriod>) —

  an Array containing a single unbounded TimezonePeriod for the time zone's constantly observed offset.

# File 'lib/tzinfo/data_sources/constant_offset_data_timezone_info.rb', line 35

def periods_for_local(local_timestamp)
  [constant_period]
end

#transitions_up_to(to_timestamp, from_timestamp = nil) ⇒ Array

Returns an empty Array, since there are no transitions in time zones that observe a constant offset.

Parameters:

• to_timestamp (Timestamp) —

  ignored.

• from_timestamp (Timestamp) (defaults to: nil) —

  ignored.

Returns:

• (Array) —

  an empty Array, since there are no transitions in time zones that observe a constant offset.

# File 'lib/tzinfo/data_sources/constant_offset_data_timezone_info.rb', line 43

def transitions_up_to(to_timestamp, from_timestamp = nil)
  []
