/*
 * timetoa.h -- time_t related string formatting
 *
 * Written by Juergen Perlinger (perlinger@ntp.org) for the NTP project.
 * The contents of 'html/copyright.html' apply.
 *
 * Printing a 'time_t' has some portability pitfalls, due to it's opaque
 * base type. The only requirement imposed by the standard is that it
 * must be a numeric type. For all practical purposes it's a signed int,
 * and 32 bits are common.
 *
 * Since the UN*X time epoch will cause a signed integer overflow for
 * 32-bit signed int values in the year 2038, implementations slowly
 * move to 64bit base types for time_t, even in 32-bit environments. In
 * such an environment sizeof(time_t) could be bigger than sizeof(long)
 * and the commonly used idiom of casting to long leads to truncation.
 *
 * As the printf() family has no standardised type specifier for time_t,
 * guessing the right output format specifier is a bit troublesome and
 * best done with the help of the preprocessor and "config.h".

/*
 * Given the size of time_t, guess what can be used as an unsigned value
 * to hold a time_t and the printf() format specifcation.
 *
 * These should be used with the string constant concatenation feature
 * of the compiler like this:
 *
 * printf("a time stamp: %" TIME_FORMAT " and more\n", a_time_t_value);
 *
 * It's not exactly nice, but there's not much leeway once we want to
 * use the printf() family on time_t values.
