int status = utc_ctime_to_date(time_t utc_ctime, std::string date, [bool output_utc])

	This routine converts a UTC ctime to a std::string having the format
	"dd-Mmm-yyyy hh:mm:ss".   Please see convert_seconds_c for the
	explanation of UTC ctimes, which is just seconds since the Epoch.
	The caller may choose to have the result as either a local time (for user
	consumption) or UTC time (for database consumption when working with
	UTC datetime DB fields).

	If the user selects local for the result the following applies:
	Because the output is in local time but without an explicit timezone
	there is an issue with regard to the duplicated local times that occur
	immediately after the transistion back to standard time each Fall.
	Like clinks_to_date this routine uses ":" vs. ";" in the time to
	distinguish the duplicated times.  Please see clinks_to_date.

	If the user selects UTC for the result the following applies
	All times are unique and the ":" vs. ";" logic is not applicable. With
	the absence of the ";" case the format is a valid Sybase date format and
	appropriate for a DB field that is intended to maintain its times in
	UTC.  See intro_database section on time and date in Sybase for details.

	utc_ctime	a time in UTC ctime
	date		std::string with result, one may use date.c_str()
			   to access results as a null terminated C string.
	output_utc	output UTC iff true (default is false for
			   similarity with clinks_to_date)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_CONVERSION_ERROR	underlying Linux routines localtime_r or
				gmtime_r failed in some way
	CLIB_BUGCHK		an internal error has occured please contact
				controls for a resolution (The expectation is
				that the user will never see this error.)

	This function requires the following include files:

	clib_h, acnet_errors_h

	Related functions:

	convert_seconds_c, clinks_to_date, intro_database, timezone_info

	C/C++ usage:

	std::string date;
	int	status;
	time_t	utc_ctime = 0;
	bool	output_utc = true;

	status = utc_ctime_to_date(utc_ctime,date,output_utc);

	fprintf(stdout,"%d (UTC ctime) is '%s' in UTC ",utc_ctime,date.c_str());
