'Usage
 

public TdPeriodTimeWithTimeZone operator +( 
   TdPeriodTimeWithTimeZone period,
   TdIntervalDayToSecond interval
)

public:
TdPeriodTimeWithTimeZone operator +( 
   TdPeriodTimeWithTimeZone period,
   TdIntervalDayToSecond interval
)

Parameters

period

A TdPeriodTimeWithTimeZone.

interval

The TdIntervalDayToSecond that will be added to the period.

Return Value

If period or the interval is Null a TdPeriodTimeWithTimeZone.Null will be returned.

When this operation is performed, the day component of the interval is ignored. Only the hour, minute, and second components are used in this operation. For example, if the period is "01:00:00-08:00, 01:30:00-08:00" and the interval is "1 02:00:00.00" (1 day, 2 hours) the add operation will result in a period of (03:00:00-08:00, 03:30:00-08:00).

When adding an interval to a TdPeriodTimeWithTimeZone it is possible that the ending bound will roll into the next 24 hours, or the beginning bound will roll into the previous 24 hours. For example, suppose the period is

   (19:32:32.3404-08:00;, 22:00:00.3232-08:00)

Adding the interval of "0 03:00:00" (3 hours) to the period will cause the ending bound to roll into the next 24 hours which will result in the invalid period:

    (22:32:32.3404-08:00, 01:00:00.3232-08:00)

Adding the interval of "-0 20:00:00" (-20 hours) to the same period will cause the beginning period to roll back into the previous 24 hours which results in the invalid period:

    (23:32:32.3404-08:00, 02:00:00.3232-08:00)

Target Platforms: Windows 8.1, Windows 10, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019
