Times formatted as "[h]:mm:ss" return ":mm:ss".

```
What steps will reproduce the problem?
1. Enter a time.
2. Format it as [h]:mm:ss.
3. Read it into php. Returns as :mm:ss. Query for format returns: ":i:s".

What is the expected output? What do you see instead?
Expect either hh:mm:ss if h!=0 or mm:ss or 0:mm:ss if h=0, not ":mm:ss".

Please provide any additional information below.
At line 1224 this project has added: $tmp =
preg_replace("/^\[[^\]]*\]/","",$tmp);. Suggest: $tmp =
preg_replace("/^\[([^\]]*)\]/","$1",$tmp);. I'm not sure why you would discard
the values inside the [], it results in improper excel date formats. In limited
tests I ran this change solved the problem. Please advise if you think I'm
overlooking something, I'm certainly no expert on excel.

This is a massively useful project btw, thanks.

Start at line 1224 and inspect how bracketed time components are handled by the format parser. Reproduce the issue with [h]:mm:ss and compare the returned value and queried format with the expected hour, minute, and second components. Done means the bracketed hour is preserved without breaking existing Excel date formats.
