Comment (by vinc17):
Yes, also assuming that {{{CHAR_BIT}}} is 8 (required by POSIX) and that
there are no padding bits. But your code is wrong, as {{{unsigned long}}}
may not be sufficient, e.g. on x32, where {{{unsigned long}}} has 32 bits
and {{{time_t}}} is defined as {{{long long}}}. But one could use:
{{{
#define TIME_T_MAX ((((time_t) 1 << (sizeof(time_t) * 8 - 2)) - 1) * 2 +
1)
}}}
