When parsing "12:00 AM", result is 12:00:00, and not 00:00:00

```
What steps will reproduce the problem?
1. Open a js console of some sort, I used chrome...
2. Type "d = Date.parse('12:00 AM');"
3. then "d.toString('HH:mm:ss');"

What is the expected output? What do you see instead?
I expect 00:00:00 but get 12:00:00

What version of the product are you using? On what operating system?
Version: 1.0 Alpha-1

Please provide any additional information below.
I'm guessing something different happens for 12:00 pm.
