I'm using this regex with

```
preg_match("/(2[0-3]|[01][0-9]):[0-5][0-9]/", $time)

```

It works fine with `05:00`, etc (with `0` leading) but i would like to accept without the `0` like `5:00` since my mysql field is TIME and accept both i would like to let people give both, since they are going to do that. 

Also this should accept `00:30` and of course not `24:30`
