ID: Q210185

The information in this article applies to:

Microsoft Access 2000

Moderate: Requires basic macro, coding, and interoperability skills.

This article applies to a Microsoft Access database (.mdb) and a Microsoft Access project (.adp).

SUMMARY

This article shows you how to create sample functions that you can use to format the Format property's Short Time setting to its decimal equivalent, to convert minutes to Short Time, or to convert Short Time to minutes.

Converting Short Time to a Decimal Format

The following sample function converts Short Time to a decimal format. In decimal format, valid time values range from .0 (00:00:00) to 999999 (23:59:59). The numeric value represents a fraction of one day. You can convert the numeric value into hours, minutes, and seconds by multiplying the numeric value by 24. This is demonstrated in step 2. To create the sample function, follow these steps:

Create a module and type the following line in the Declarations section if it is not already there:


Option Explicit

Type the following procedure:


Function TimeToDec(MyTime)
   TimeToDec = CDbl(MyTime) * 24
End Function

To test this function, type the following line in the Immediate window, and then press ENTER:
```
?TimeToDec(#6:30#) 
```
Note that the Immediate window returns 6.5.

NOTE: If you do not multiply CDbl(MyTime) by 24, the Immediate window returns 0.270833333333333

Converting Minutes to Short Time Format

To create a sample function that converts minutes to the Short Time format, follow these steps:

Create a module and type the following line in the Declarations section if it's not already there:


Option Explicit

Type the following procedure.


Function MinToTime(MyMinute)
   MinToTime = MyMinute \ 60 & ":" & Format((Abs(MyMinute Mod 60)),"00")
End Function

To test this function, type the following line in the Immediate window, and then press ENTER:
```
?MinToTime(390) 
```
Note that the Immediate window returns 6:30.

Converting Short Time to Minutes

To create the sample function that converts Short Time to minutes, follow these steps:

Create a module and type the following line in the Declarations section if it's not already there:


Option Explicit

Type the following procedure:


Function TimeToMin (MyTime)
   TimeToMin = CInt(CDbl(MyTime) * 24 * 60)
End Function

To test this function, type the following line in the Immediate window, and then press ENTER:
```
?TimeToMin(#6:30#) 
```
Note that the Immediate window returns 390.
