Public Member Functions

• Offset ()

  Default constructor.
  

• Offset (long utcOff)

  Implicit constructor with seconds east of UTC.
  

• bool isSet () const

  Flag if the offset to UTC is defined.
  

• long utcOff () const

  Seconds east of UTC: timestamp - UTC.
  

Private Types

• notSet = 0

  Undefined: system time.
  

• gmtOnly

  Only offGmt_ is valid.
  

• gmtSys

  offGmt_ and offSys_ have been computed.
  

• enum Status { notSet = 0, gmtOnly, gmtSys }

  The status of the offset. More...
  

Private Attributes

• Status status_

  The status of the offset.
  

• long offGmt_

  Seconds east of GMT.
  

• long offSys_
