Replace each "?" in there with [0-9] and it should work.

No, ? will match the preceeding expression once or not at all, it's
definitely not what you want in this case.

use (re-search-forward "^??/??/?? ??:??:??:") to search for a
time stamp like the following
09/21/03 09:48:51: anything else
But it fails. Can anyone point out what is wrong? Thanks in advance.

This works. But does ? cover all characters in [0-9]?

Replace it with (re-search-forward "^../../.. ..:..:..:")

That look like a shell glob. In shell globs, ? stands for any single
character (except /), whereas * stands for zero or more characters
(except /).
Regular expressions work differently: . stands for any single
character (except newline), and ?, + and * are suffixes.
a? means zero or one occurrences of a.
a+ means one or more occurrences of a.
a* means zero or more occurrences of a.
Thus, ".*" means zero or more occurrences of any character, which is
similar to the shell glob "*".
And "." means any single character, which is similar to the shell glob
"?".
