Why is wtmp so big?

[Rick Farris]

In my never-ending search for disk space, I have discovered
/etc/wtmp, which is a whopping 4,184,424 bytes long.  Is this normal?

Is this a "log" file, composed of numerous /etc/utmp entries?  Can I
truncate it by copying /etc/utmp to it?  Can I delete it altogether,
and let it recreate itself?

Inquiring (disk-hungry) minds want to know.
