>Subject: [PATCH] Fix bug #7785 - atime limit.
>
>On a 64-bit time_t system make MAX_TIME_T the max value that
>can be represented in a struct tm. This allows applications to
>set times in the future beyond the 32-bit time_t limit (2037).
>
>This is only in source3/configure.in, needs adding to the waf
>configure/build system (but I'll need help with that).
