In an ISO 8601 date, is the T character mandatory?
I'm wondering if the following date is ISO8601 compliant :
2012-03-02 14:57:05.456+0500
(for sure, 2012-03-02T14:57:05.456+0500 is compliant, but not that much human readable !)
IOW, is the T between date and time mandatory ?

Are there any non-twos-complement implementations of C?
As we all no doubt know, the ISO C standard (and C++ as well, I think, though I'm more interested on the C side) allows three underlying representations of signed numbers:
