 Revision history for Perl extension Time::HiRes.
 
+1.78   [2005-10-03]
+       - ITIMER_VIRTUAL detection in HiRes.t had problems (that we cannot
+         in the general case fail already at 'use' is suboptimal)
+       - fixes to the documentation of clock_gettime() and clock_getres()
+
 1.77   [2005-10-03]
        - add support for the POSIX clock_gettime() and clock_getres(),
          if available, either as library calls or as syscalls
