* - lpFormat is a string of characters and formatting tokens. Any characters

* - The following tokens have special meanings in a time format string:
*| Token Meaning
*| ----- -------
*| h Hours with no leading zero (12-hour clock)
*| hh Hours with full two digits (12-hour clock)
*| H Hours with no leading zero (24-hour clock)
*| HH Hours with full two digits (24-hour clock)
*| m Minutes with no leading zero
*| mm Minutes with full two digits
*| s Seconds with no leading zero
*| ss Seconds with full two digits
*| t Short time marker (e.g. "A" or "P")
*| tt Long time marker (e.g. "AM", "PM")
* - To output any literal character that could be misidentified as a token,
* enclose it in single quotes.
