I've got an application that goes through apache log files, and one of
the things is does is parse the dates. However, I'm getting mysterious
ocassional failures on what seem to be random lines, different every
time, and a line that wouldn't parse will start parsing when I put it
into a test case.
Here's the stacktrace, in this case I did a "Date.new(2003, 4, 11)":
Exception: Couldn't parse date 2003-4-11 (11/Apr/2003): NaN
/usr/local/lib/ruby/1.8/date.rb:300:in `floor'
/usr/local/lib/ruby/1.8/date.rb:300:in `civil_to_jd'
/usr/local/lib/ruby/1.8/date.rb:568:in `valid_civil?'
/usr/local/lib/ruby/1.8/date.rb:590:in `new'
./HttpLogRecord.rb:83:in `parse_apache_date'
./HttpLogRecord.rb:36:in `parse'
...
This happens both with 1.8.1 and 1.8.2preview2. Any thoughts?

That is quite odd, I cannot recreate it on my machine. Although,
digging through the source code makes me think it might be a C library
issue with your "math.h" implementation. Granted I am nowhere close
to knowledgeable when it comes to this level of detail. So in order
to help the ones in the know; What is your output when you type
"ruby -v" ?
Best,

Just for comparison's sake, here are the details of the machine I ran it on:
$ ruby -v
ruby 1.8.2 (2004-05-24) [i686-linux]
$ uname -a
Linux TwinStar 2.4.20-8smp #1 SMP Thu Mar 13 17:45:54 EST 2003 i686 i686 i386
GNU/Linux
If I get some time this weekend I might boot up my Sparc 5 with NetBSD and see
what it does. But, hopefully someone in the know will answer the problem
before then
Best,
Zev

Ah, no I did not. Although, I just tried it with the following code
with no problems.
