This article shows you how to create sample functions that you can use toformat the Format property's Short Time setting to its decimal equivalent, to convert minutes to Short Time, or to convert Short Time to minutes.Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.
The following sample function converts Short Time to a decimal format. Indecimal format, valid time values range from .0 (00:00:00) to999999 (23:59:59). The numeric value represents a fraction of one day. Youcan convert the numeric value into hours, minutes, and seconds bymultiplying the numeric value by 24. This is demonstrated in step 2. Tocreate the sample function, follow these steps:
Create a module and type the following line in the Declarations section if it is not already there:
Type the following procedure:
Function TimeToDec(MyTime) TimeToDec = CDbl(MyTime) * 24End Function
To test this function, type the following line in the Immediate window, and then press ENTER:
Note that the Immediate window returns 6.5.
NOTE: If you do not multiply CDbl(MyTime) by 24, the Immediate window returns 0.270833333333333
