  Sample input:
Military Time ( 4:40:36 PM )
  Sample output:
1640

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

This function gives an HHMM display of a Filemaker time capture fields in the format of HH:MM:SS xM where x="A" or "P" (for the before or after 12 noon AM or PM).

This function converts to military (24-hour) time and also removes the colons and seconds display. This function could be changed slightly to include the display of seconds by searching for the second colon and taking the two digits to the immediate right of the second colon.

How about:

SerialIncrement ( "0000" ; 100 * Hour ( time ) + Minute ( time ) )

I have this to convert a military entry in to a time field without manually entering the colon separators.

Time( Left( Self ;Choose( Length( Self );0;1;2;1;2));
Right( Self ;Choose( Length( Self );0;0;0;2;2));
0)

This simple calc works great, except, I NEED the seconds included. The calc above drops the seconds to "00". Also, It won't allow an alteration of a "MM" or "HH" if incorrectly entered. The entire time must be re-entered. Can you help?

This is what I need:

Entry: "235120"
Result: "23:51:20

Disregard the previous post/comment, I found the calc I was looking for on one of your other pages.

This doesn't work between 1200 noon and 1259. It outputs 2400 to 2459.

This is poorly written. I wouldn't use this at all. It should be wrapped in a GetAsTime, there is a much simpler way to do things other than Right & Left and as stated this doesn't work in 100% of the cases.

DO NOT USE.
