'Usage
 

public TdPeriodTimestampWithTimeZone operator -( 
   TdPeriodTimestampWithTimeZone period,
   TdIntervalDayToSecond interval
)

public:
TdPeriodTimestampWithTimeZone operator -( 
   TdPeriodTimestampWithTimeZone period,
   TdIntervalDayToSecond interval
)

Parameters

period

A TdPeriodTimestampWithTimeZone.

interval

The TdIntervalDayToSecond that will be subtracted from the TdPeriodTimestampWithTimeZone.

Return Value

If interval or period is Null a TdPeriodTimestampWithTimeZone.Null will be returned.

The TdIntervalDayToSecond will be subtracted from both the beginning and ending bounds of the period. If the scale between period and the interval is different, the arithmetic operation will be performed using the different scales. The result will then be truncated to match the scale of the TdPeriodTimestampWithTimeZone.

For example, if the period is "2007-10-04 12:50:56.2123-08:00", "2007-11-01 13:23:54.4435-08:00") and the interval is "200 20:40:50.654321" (200 days, 20 hours, 40 minutes, 50 seconds and 654321 microseconds), the subtract operation will result in a period of ("2007-03-17 16:10:05.5579-08:00", "2007-04-14 16:43:03.7891-08:00").
