That's also my point.
If some people think that having below day date precision is a bad thing,
then they can simply ignore that precision by manipulating only days-rounded
datetimes. I understand correctly the problems with UTC and leap seconds,
but I think that having a 22seconds difference over a 30 years time period
is not a big problem unless you're doing very precise calculations, and then
we can eventualy put a warning in the library docs for such users, while
still helping a lot of people with date/time manipulation.

Concerning the precision of floats, using an Int64 is sure a better thing as
Brian showed it.

I also agree with :
type locale = (day -> string) * (month -> string)
from Achim . This way the library can be more easily extended with specific
or exotic printers ( a startrek time pp anyone ? )
