public TdTime Subtract( 
   TdIntervalDayToSecond interval
)

public:
TdTime Subtract( 
   TdIntervalDayToSecond interval
) 

Parameters

interval

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

Return Value

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

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

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, adding 2 hours to "23:54:00" will result in a TdTime value of "01:54:00".

If the scale between this instance of TdTime 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 TdTime. 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 TdTime value of "12:50:56.2123" the operation will result in a TdTime value of "02:25:15.5999".
