'Declaration
 
Public Overloads Function Subtract( _
   ByVal timeSpan As TimeSpan _
) As TdTimeWithTimeZone

'Usage
 
Dim instance As TdTimeWithTimeZone
Dim timeSpan As TimeSpan
Dim value As TdTimeWithTimeZone
 
value = instance.Subtract(timeSpan)

public TdTimeWithTimeZone Subtract( 
   TimeSpan timeSpan
)

public:
TdTimeWithTimeZone Subtract( 
   TimeSpan timeSpan
) 

Parameters

timeSpan

The TimeSpan that will be subtracted.

Return Value

If this instance of TdTimeWithTimeZone is Null a TdTimeWithTimeZone.Null is returned.

The TimeSpan object can contain data about the number of days, hours, minutes, seconds, and fractional seconds. 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 "23:54:00-08:00".

If the scale between this instance of TdTimeWithTimeZone and the timeSpan 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 time. For example, the subtraction operation

TdTime.Parse("12:48:53.2123+08:00") - TimeSpan.Parse("00:02:03.00009")

results in a TdTime value of "12:46:50.2122+08:00".

A TimeSpan can have a scale up to 7. A TdTimeWithTimeZone has a maximum scale of 6. When performing an arithmetic operation, only the first 6 digits to the right of the decimal point of the TimeSpan operand will be considered. The 7th digit will be ignored.
