I need to export text that shows date and time in the format : "yyyy-mm-dd hh:mm:ss" The best formula I have found so far for the calculation field is

"Year ( DateStart ) & "-" & Month ( DateStart ) & "-" & Day ( DateStart )& " " & TimeStart"

However this gives results like ""2012-4-23 10:00:00" which has the problem of the month only having one digit when I need it to have two. Any ideas for resolving this?

I also have the problem that the exported text should have a UNIX LF end of carriage instead of a Macintosh end of line. Can you implement a UNIX LF end of carriage from within FMP?

Use this expression to add leading zeros...

Right( "00" & Month( DateStart ) ; 2 )

Let ( [

  Date = YourDate ;

       y = Year ( Date ) ;

      m = Right ( 0 & Month ( Date ) ; 2 ) ;

       d = Right ( 0 & Day ( Date ) ; 2 )

] ;

    y & "-" & m & "-" & d

)

Great thanks very much to both of you. Any ideas about the LF end of carriage problem ?

When exporting data (suit the Export script step) there is an option to choose Macintosh or Windows format.
