+dnl In the presence of a high resolution realtime timer Erlang can adapt
+dnl its view of time relative to this timer. On solaris such a timer is
+dnl available with the syscall gethrtime(). On other OS's a fallback
+dnl solution using times() is implemented. (However on e.g. FreeBSD times()
+dnl is implemented using gettimeofday so it doesn't make much sense to
+dnl use it there...) On second thought, it seems to be safer to do it the

+dnl In the presence of a high resolution realtime timer Erlang can adapt
+dnl its view of time relative to this timer. On solaris such a timer is
+dnl available with the syscall gethrtime(). On other OS's a fallback
+dnl solution using times() is implemented. (However on e.g. FreeBSD times()
+dnl is implemented using gettimeofday so it doesn't make much sense to
+dnl use it there...) On second thought, it seems to be safer to do it the
