* GetTimeFormatA [KERNEL32.@]
*
* Format a time for a given locale.
*
* PARAMS
* lcid [I] Locale to format for
* dwFlags [I] LOCALE_ and TIME_ flags from "winnls.h"
* lpTime [I] Time to format
* lpFormat [I] Formatting overrides
* lpTimeStr [O] Destination for formatted string
* cchOut [I] Size of lpTimeStr, or 0 to calculate the resulting size
*
* NOTES
* - If lpFormat is NULL, lpszValue will be formatted according to the format
* details returned by GetLocaleInfoA() and modified by dwFlags.
* - lpFormat is a string of characters and formatting tokens. Any characters
* in the string are copied verbatim to lpTimeStr, with tokens being replaced
* by the time values they represent.
* - 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.
* - The ANSI version of this function fails if lcid is Unicode only.
*
* RETURNS
* Success: The number of character written to lpTimeStr, or that would
* have been written, if cchOut is 0.
