Date Practice
Parsing dates is the programmer's equivalent of doing your taxes - you've got to do it, it's fidly and easy to get wrong, and you want it quick and painless.
Previously I'd read package time, got confused
by the reference time layout Mon Jan 2 15:04:05 MST 2006
and fought my
way through various StackOverflow Questions. Or used
imetakeule/fmtdate.
Hence I wrote these exercises for myself, and I now find Golang's date parsing very logical and easy (excepting some corner cases). Hopefully the exercises will be of use to others. I'm interested in more questions - pull requests welcome.

Instructions
git clone https://github.com/soniah/date_practice
go test
Edit dates_test.go
until all tests pass.
Many of the dates were printed out using time.Format()
with the provided
common layout strings. You could of course use these layouts to parse the
dates but you wouldn't learn much. Instead write your own layouts.
My answers are in the branch answers
but no peeking!
Where the dates don't have timezones they in are in Hong Kong time.
Hints
-
when parsing difficult dates you can build up the layout chunk-by-chunk - time.Parse() will print out the remaining unmatched text
