public TdTimeWithTimeZone Subtract( 
   TdIntervalDayToSecond interval
)

public:
TdTimeWithTimeZone Subtract( 
   TdIntervalDayToSecond interval
) 

Parameters

interval

A TdIntervalDayToSecond that will be subtracted from this instance of TdTimeWithTimeZone.

Return Value

If interval or this instance of TdTimeWithTimeZone is Null a TdTimeWithTimeZone.Null will be returned.

The TdIntervalDayToSecond interval will be subtracted from this instance of TdTimeWithTimeZone.

The TdIntervalDayToSecond interval may contain data about the number of days, hours, minutes, seconds, and sub-seconds. The days will be discarded during all calculations. If the time rolls into the next or previous day, the result will only contain the time component. For example, subtracting 2 hours from "01:54:00-08:00" will result in a TdTimeWithTimeZone value of "23:54:00-08:00".

If the scale between this instance of TdTimeWithTimeZone and the interval parameter are different, the arithmetic operation will be performed using the different scales. The result will then be truncated to match the scale of the TdTimeWithTimeZone. For example, if the TdIntervalDayToSecond value of "222 10:25:40.61234" (222 days, 10 hours, 25 minutes and 40.61234 seconds) is subtracted from the TdTimeWithTimeZone value of "12:50:56.2123:08:00" the operation will result in a TdTimeWithTimeZone value of "02:25:15.5999+08:00".

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