In both sandbox and production, no report can be customized or created as all date filters or date entries read as `invalid date`. Locale is US English

**Fails - new or customize any report**

Also - If you select a date from the date picker, no date is populated (or is invisible)

**Works - run existing reports**

Existing reports will execute and their date filters can be changed from the Report page but they can't be customized; no new reports can be created.

Looks like a SFDC bug to me.

Anyone else seen this?
