I used NetBSD as a reference when I needed a cross platform strptime that behaved identical everywhere. I found the source very approachable. Source was well laid out and fairly clear. Some of it was subjectively a bit ugly to just look at, but when you read it, it was very clear. Couldn't use glibc as a reference because this in a closed source commercial product and, well, GPL.
