There's another reason to keep your computer well-synched, and that's
if you're performing micro-benchmarks.  If you're really interested in
how many microseconds something takes (say because you're going to
scale it by a factor of several million), then you'd like to know at
what rate your clock tends to drift, and by how much that varies.

If you're just interested in having a reasonably accurate clock
(within a minute), then you certainly need less precision.
