Truncating leading zeroes

[JM]

When I enter time such as 0600 and then tab, the leading zero disappears
leaving 600. Any suggestions on how to correct this problem?

I assume that you are talking about a protected online form.
Unprotect>Double click the field>Type "Number">Number format "####"

I'm preparing a simple travel itinerary in a new document when this problem

I got it to work by formatting the cell for time and changing the locale to
English (United Kingdom), but I'm not sure what else that might do.
