Yes, if I want to display sub-second printing. But I was just looking
at the rounding behavior.

In wha
Stavros,
Two really quick comments:

b) AFAIK pre-epoch times are second-class citizens

POSIXct/lt supports fractional seconds (see Sub-second Accuracy
section of man page), but there seem to be some inconsistencies in
their handling.
Converting to POSIXlt and back does not give back the same time for
times before the origin:
