Public Overloads Function Subtract( _

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

public TdPeriodTimestamp Subtract( 
   TdIntervalDayToSecond interval
)

public:
TdPeriodTimestamp Subtract( 
   TdIntervalDayToSecond interval
) 

Parameters

interval

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

Return Value

If interval or this instance of TdPeriodTimestamp is Null a TdPeriodTimestamp.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 TdPeriodTimestamp 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 TdPeriodTimestamp.

For example, if the period is "2007-10-04 12:50:56.2123", "2007-11-01 13:23:54.4435") 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", "2007-04-14 16:43:03.7891").

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