Found when this code was introduced:

=======
Revision 1.186 / (download) - annotate - [select for diffs], Fri Mar 25
01:56:12 2005 UTC (7 months, 3 weeks ago) by marcel
Branch: MAIN

Fix inittodr() invocation. Now that devfs is mounted before the
actual root file system is mounted, the first entry on the mountlist
is not the root file system and the timestamp for that entry is
typically 0. Passing that to inittodr() caused annoying errors on
alpha and ia64.
So, call inittodr() for all file systems on mountlist, but only when
the timestamp (mnt_time) is non-zero.
