I seem to remember having similiar issues with the time structure myself.
I can't remember whether I was porting code from unix to windows, or from one type of unix to another or (most likely) recompiling on a higher version of HP-UX.
It seems the time.h and its structures are not standard across the board and you may have to compile slightly different code based on your environment.
As Perderabo suggests you may need to examine the different compile switchs already available in your headers, or
use your own pre-processor directives to conditionally compile code, or
write your own time functions and use them instead.

Just a thought that entered my mind when learning about structs.
First thought was:
struct one

struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)

timerisset
TIMERADD(3) BSD Library Functions Manual TIMERADD(3)
NAME
timeradd -- operations on time structure
SYNOPSIS
#include <sys/time.h>
void
timeradd(struct timeval *a, struct timeval *b, struct timeval *res);
void
timersub(struct timeval *a, struct timeval *b, struct timeval *res);
void
timerclear(struct timeval *tv);
int
timerisset(struct timeval *tv);
int
timercmp(struct timeval *a, struct timeval *b, CMP);
void
timespecadd(struct timespec *a, struct timespec *b, struct timespec *res);
void
timespecsub(struct timespec *a, struct timespec *b, struct timespec *res);
void
timespecclear(struct timespec *ts);
int
timespecisset(struct timespec *ts);
int
timespeccmp(struct timespec *a, struct timespec b, CMP);
DESCRIPTION
These macros are provided for manipulating the timeval and timespec structures described in timeval(3).
The timeradd() and timespecadd() macros add the time information stored in a to b, storing the result in res. With timeradd() the results
are simplified such that the value of res->tv_usec is always less than 1,000,000 (1 second). With timespecadd() the res->tv_nsec member of
struct timespec is always less than 1,000,000,000.
The timersub() and timespecsub() macros subtract the time information stored in b from a and store the resulting structure in res.
The timerclear() and timespecclear() macros initialize the structures to midnight (0 hour) January 1st, 1970 (the Epoch). In other words,
they set the members of the structure to zero.
The timerisset() and timespecisset() macros return true if the input structure is set to any time value other than the Epoch.
The timercmp() and timespeccmp() macros compare a to b using the comparison operator given in CMP. The result of the comparison is returned.

HISTORY
The timeradd() family of macros first appeared in NetBSD 1.1. These were later ported to FreeBSD 2.2.6. The timespec() family of macros
first appeared in NetBSD 1.2.
