+.Sh NAME
+.Nm inittodr
+.Nd initialize system time
+.Sh SYNOPSIS
+.Ft void
+.Fn inittodr "time_t base"
+.Sh DESCRIPTION
+The
+.Fn inittodr
+function determines the time and sets the system clock.
+It tries to pick the correct time using a set of heuristics that examine
+the system's battery-backed clock and the time reported by the file
+system, as given in
+.Fa base .
+Those heuristics include:
+.Bl -bullet
+.It
+If the battery-backed clock has a valid time, and is not significantly
+behind the time provided by
+.Fa base ,
+it is used.
+.It
+If the battery-backed clock does not have a valid time, or is significantly
+behind the time provided in
+.Fa base ,
+and the time provided in
+.Fa base
+is within reason,
+.Fa base
+is used as the current time.
+.It
+If the battery-backed clock appears invalid, and
+.Fa base
+appears non-sensical or was not provided (was given as zero),
+an arbitrary base (typically some time within the same year that
+the kernel was last updated) will be used.
+.El
+.Pp
+Once a system time has been determined, it is stored in the
+.Va time
+variable.
+.Sh DIAGNOSTICS
+The
+.Fn inittodr
+function prints diagnostic messages if it has trouble figuring
+out the system time.
+Conditions that can cause diagnostic messages to be printed include:
+.Bl -bullet
+.It
+There is no battery-backed clock present on the system.
+.It
+The battery-backed clock's time appears nonsensical.
+.It
+The
+.Fa base
+time appears nonsensical.
+.It
+The
+.Fa base
+time and the battery-backed clock's time differ by a large amount.

+.Sh BUGS
+Some systems use heuristics for picking the correct time that are slightly
+different.
