[ospfd] Bug #134, ospfd should be more robust to backward time change
2006-08-25 Paul Jakma <paul.jakma@sun.com>
* (general) Bug #134. Be more robust to backward time changes,
use the newly added libzebra time functions.
In most cases: recent_time -> recent_relative_time()
gettimeofday -> quagga_gettime (QUAGGA_CLK_MONOTONIC, ..)
time -> quagga_time.
(ospf_make_md5_digest) time() call deliberately not changed.
(ospf_external_lsa_refresh) remove useless gettimeofday, LSA
tv_orig time was already set in ospf_lsa_new, called via
ospf_external_lsa_new.
