Instance Method Summary

DataTimezoneInfo - Inherited

#create_timezone, #period_for,
#periods_for_local

Returns an Array containing the TimezonePeriods that could be observed at the local time specified by local_timestamp.
#transitions_up_to

Returns an Array of ::TZInfo::TimezoneTransition instances representing the times where the UTC offset of the time zone changes.
#raise_not_implemented

Raises a NotImplementedError to indicate that the base class is incorrectly being used directly.

TimezoneInfo - Inherited

#create_timezone, #inspect,
#raise_not_implemented

Raises a NotImplementedError.

Constructor Details

.new(identifier, constant_offset) ⇒ ConstantOffsetDataTimezoneInfo

Initializes a new ConstantOffsetDataTimezoneInfo.

The passed in identifier instance will be frozen. A reference to the passed in ::TZInfo::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.

Parameters:


    
  
  •

    • 



Returns:


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