Re: Emacs current-time-string core dump on 64-bit hosts

    But the current time might be out of ctime's range for many reasons:

      * a hardware problem (the hardware clock jumped far in the future or past)
      * a software problem (a bug in the 'date' program's date parser, say)
      * a human error (someone set the date incorrectly).

It seems unlikely to me that these things will be able to set the system's time
to a value the system can't handle.  More likely the time will get truncated
into the range the system can handle.  For instance, if someone specifies
an out-of-range date, it will probably be truncated into a reasonable date.
It will just be incorrect.

Meanwhile, the system will probably crash due to demons that use ctime.
