You should not try to control the format as it is being constructed;
it's better to check that the field is valid before it is used. See
<URL:http://www.merlyn.demon.co.uk/js-valid.htm> and use something like
OK = /^\d\d[:\.]\d\d$/.test(S)
If those are times, maybe /^[0-2]\d[:\.][0-5]\d$/ - it's scarcely worth
bothering to rule out hours 24..29.
