oh I see - I fell into that trap before (with sleep) where the function
naming/doc wording suggest a second granularity. I should stop looking at
function names and start looking at parameter types. Sorry for that and
thanks again!

I'm confused by the question. Maybe you have and old version where
'seconds->date' accepts only integers? The current version accepts a real,
and so fractional seconds can be in the argument to 'seconds->date'.

seconds->date for milliseconds (didn't find one in the docs)? Once more,
what I need to do is examine the timing relationship between different
applications one of which is Racket and the other isn't (but uses the
system clock on a fine granularity). Thus I need absolute timing in my
Racket app...
Thanks!

Use `current-inexact-millseconds' (and divide by 1000) instead of
`current-seconds'.

I need a millisecond granularity though (or at least 100 ms) -
GetSystemTime() provides that...
Thanks!

I think you want `current-seconds' and `seconds->date' (where the
latter lets you pick local or UTC).
