[Design] Fwd: Regular expressions for date/time widget

[Mimi Yin]

Forwarding to the design list...as an FYI

Darshana and I have put together a laundry list of the regular  
expressions handled by the new date/time Natural Language Processor  
that was checked in last week?

Both Bear, Darshana have amended the wiki page with comments.

If your curious, take a look and add your own use cases in the  
Comments section at the bottom.

Thx!

Mimi
