Revision 1.7, Sat Dec 10 04:12:36 2011 UTC (12 years, 6 months ago) by guenther
Branch: MAIN
CVS Tags: OPENBSD_5_3_BASE, OPENBSD_5_3, OPENBSD_5_2_BASE, OPENBSD_5_2, OPENBSD_5_1_BASE, OPENBSD_5_1 Changes since 1.6: +2 -6 lines
Use clock_gettime() to get a high precision timestamp, instead of
converting gettimeofday()'s output, and pass utimes() NULL to get
the time from inside the kernel instead
ok espie@, stress testing on NFS by deraadt@
