[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!
