/*******************************************************************************
* wceex_ctime - Convert a time value to a date and time string
*
* Description:
*
* The ctime function is similar to asctime, except that you specify
* the calendar time argument as a time_t simple time value rather
* than in broken-down local time format.
* It shall be equivalent to: asctime(localtime(clock))
*
* The ctime() is not required to be thread-safe.
*
* Windows CE specific:
* ctime does not set the variable tzname.
*
* Reference:
*
* IEEE Std 1003.1-2001
* The GNU C Library Manual
*
