Summary: time_t  can be unsigned

Initial Comment:
On recent versions of OpenVMS, time_t is defined as:

SYS$COMMON:[DECC$LIB.REFERENCE.DECC$RTLDEF]TIME.H;1

     typedef unsigned long int time_t;


The compiler's complaint is as follows:

        if (mtime == -1)
............^
%CC-I-QUESTCOMPARE1, In this statement, the unsigned
 expression "mtime" is being compared with an equality
 operator to a constant whose value is negative.  This
 might not be what you intended.
at line number 715 in file IMPORT.C


>>> import time
>>> time.ctime(0x7fffffff)
'Tue Jan 19 03:14:07 2038'
>>> time.ctime(0x80000000)
'Tue Jan 19 03:14:08 2038'
>>> time.ctime(0xfffffffe)
'Sun Feb  7 06:28:14 2106'
>>> time.ctime(0xffffffff)
'Sun Feb  7 06:28:15 2106'
>>>

What does OpenVMS use for an "invalid" value for the time_t type?  Where can we find more specific information about this issue for OpenVMS?
