Feature Request: distinguish between ';now;' and ';today;'

[cori]

As I mentioned elsewhere, the semicolon workaround for NLP dates is very useful and solves a few problems for me - enough so I could reenable the extension, so thanks for that!

Given that, I'd really love for ;now; to return the current date and time and ;today; to parse to just the date, instead of them both parsing to the same value.
