StudyTime Input:

The studytime infobox parameter accepts two formats. An Hour-float (studyTime = H.hhhh) or a Time-code (studyTime = H:M).

Proper input rules:
H.hhhh: (Dot delimited) At least one leading digit, and at least 4 decimal digits.(good: "0.1230", bad: ".123")
H:M: (Colon delimited) At least one hour digit, and 1 or 2 minute digits. (good: "0:1", bad: ":1" or "0:123")

(Although bare integer-input would work for both format cases, there currently deemed improper formatted input.)
