[Gcl-devel] Re: [Maxima] computation time information

[Camm Maguire]

Greetings!  At least on unix, we have:

>(si::gettimeofday)

1.1666460602236531E9

for microsecond resolution.  Perhaps you could suggest a patch?  We
are in need of a windows developer.  Specifically, there is a windows
specific read.d patch which needs reverting and testing -- I've asked
several people to test but have received no replies.  I'd like to get
this out before 2.6.8 is release if possible.  

The patch should be on the mailing lists.  Out of the office for one
week.  Would be absolutely wonderful if someone could try this by
then. 

Take care,
