'Usage
 
Dim instance As TdPeriodTimestampWithTimeZone
Dim interval As TdIntervalDayToSecond
Dim value As TdPeriodTimestampWithTimeZone
 
value = instance.Subtract(interval)

public TdPeriodTimestampWithTimeZone Subtract( 
   TdIntervalDayToSecond interval
)

public:
TdPeriodTimestampWithTimeZone Subtract( 
   TdIntervalDayToSecond interval
) 

Parameters

interval

The TdIntervalDayToSecond that will be subtracted from this instance of TdPeriodTimestampWithTimeZone.

Return Value

If interval or this instance of TdPeriodTimestampWithTimeZone 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 this instance of TdPeriodTimestampWithTimeZone 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").

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