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'.

but is there a conversion function to the system time similar to
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
Use `current-inexact-millseconds' (and divide by 1000) instead of
`current-seconds'.

For example,
I imagine that there were questions and answers about getting Racket to
access PLT Scheme collections.
I'd like to look for these on users@racket-lang.org archives but this seems

You should not have to change the suffix.
If you require a path that ends in ".ss" and the file doesn't exist,
then the error will be reported in terms of an ".rkt" suffix (since the
module loader tries both). So, just to be sure, the file
"/DG/programs/accounts/email-exists.ss" does exist, right?
Hi,
The first line below shows my command line entry. The remaining lines show
the result.
Obviously, Racket is looking for a .rkt version of my .ss file. Do I
really have to change my extensions? There must be a better way.
Thanks

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

After converting solution files from VS2008 to VS2010, I get errors like

Hi there,
I need to compare time events in my Racket application against output from a
third-party application that most probably uses GetsystemTime() or
GetLocalTime() for its time stamps, so I need to access those functions as well
(or other functions that contain the same information).
