Datatype for time

I want to import an Excel file that contains time in the format below.  I want to do calculations on time (like how many minutes),


Again, so I want to add this to access and be able to sum up and say, for example, that it was 3 hours or 25 minutes, etc...

I'm (1) not sure what data type and (2) how I may be able to sum up.

I attached a sample if it helps.

Thank you

Just be able sum them up would probably work.

1. Import the Excel File
2. Create a query like this:
SELECT Sum([YourMinutesField]) AS TotalMinutes
FROM YourTable;
3. Set the format property of this filed to: hh:nn:ss

This will give you:  0:12:37 the result for those numbers
(12 minutes, 37 seconds)

Don't let you confuse; it's not about the format, it's about the data type.

And the data type for date and/or time in Access is Date.

Jeffrey CoachmanMIS LiasonCommented:
...or you can create an expression:

And use that as the controlsource for a textbox:
...Then set the format property of this textbox to:  hh:nn:ss
Gustav BrockCIOCommented:
To sum time periods, just sum these.
If the total is within 24 hours, that's all.

If more then 24 hours, and you wish a display like 34:15, use a function like this:
Public Function FormatHourMinute( _
  ByVal datTime As Date, _
  Optional ByVal strSeparator As String = ":") _
  As String
' Returns count of days, hours and minutes of datTime
' converted to hours and minutes as a formatted string
' with an optional choice of time separator.
' Example:
'   datTime: #10:03# + #20:01#
'   returns: 30:04
' 2005-02-05. Cactus Data ApS, CPH.

  Dim strHour       As String
  Dim strMinute     As String
  Dim strHourMinute As String
  strHour = CStr(Fix(datTime) * 24 + Hour(datTime))
  ' Add leading zero to minute count when needed.
  strMinute = Right("0" & CStr(Minute(datTime)), 2)
  strHourMinute = strHour & strSeparator & strMinute
  FormatHourMinute = strHourMinute
End Function

<I'm (1) not sure what data type and (2) how I may be able to sum up.>

When you import your table to Access, ...Access should set the data-type as "Date\Time".
However, it might display an odd date as well.
You can cure this by setting the format property of the field to: hh:nn:ss
