I don't think there is any real standard way to enter either times or time
intervals - what I do is use a straight edit box which allows several alternate
formats and convert the entry on the onexit event,
eg I can allow times like 1:10pm to be entered as
13:10
1:10pm
or time intervals can be entered as eg for 1 hour 30 mins
1:30:00
1:30 (may need to be smart here, you may want sometimes to interpret this
as 1 min 30 sec)
1h30
Means you have to write your own convert text to time routine, but can make it
really smart and easy to enter text into. Never much used mask edit as I found
it too puzzling to set up formats for cases like this, the help was not much
help.
Sunbird (Thunderbird calendar add-on) has a rather neat way to enter times - it
gives a list of times through the hour that can be expanded or shrunk to get
more detail - but its not standard.
I think even if there was a component I might hesitate to use it for the
reasons of "Will this make it hard to upgrade my Delphi version?"
