You must do also a localtime_r after this call.
clock_gettime returns the same time as gettimeofday.
But point IS in comparing clock_gettime() vs. gettimeofday() which is used by
fpgettimeofday(). I don't see localtime_r() calls in current RTL Now().
Ok.
It turns out that Now() was doing a fpGettimeofday (for time) and a fptime (for
date), which is of course really stupid.
I improved that (it does one call only). So, new stats, 64-bit, no
optimizations:
sb: >./unixclocks
RTL Now() with 10000000 calls = 3698 ms
Kernel clock_gettime() NowReal() with 10000000 calls = 6564 ms
Revision 19572.
The time is now less than the Libc time you posted (5085ms).
I can't test the libc version, but if you'd care to re-test using the above
revision of unix/sysutils.pp, and post the results, I'd be grateful.
Michael.
