Well, your question certainly prompted me to go and read up on it again.
 In my work (unmanned space missions - solar system stuff), we deal with
many representations of time, and so I am used to being anal about it.
For example, there is GMT, UTC, TDT, ET, etc.  They all differ ever so
slightly.

Indeed!  Thanks, I'll put this in the patch.  The above is actually not
needed for the mount command or /etc/mtab, but it *is* used for, e.g.,
/proc/mounts.
