I'm creating a database with SQLAlchemy and SQLite. I have some database models and one of them needs a time. Not the time-of-the-day sort of time but like when-you-study-for-10-minutes sort of time. What format can we store in db.Time? Code:

time = db.Column(db.Time, nullable=False)

What you're looking for is a "time interval". SQLite doesn't have that. In fact, it doesn't have a time type at all. So use whatever you want.

I would suggest storing the number of seconds in the interval as an integer. For "15 minutes" you would store 900.

SQLAlchemy does have an Interval type for storing datetime.timedelta objects which you could try. The docs say "the value is stored as a date which is relative to the “epoch” (Jan. 1, 1970)" which I think is just a fancy way to say they'll store the number of seconds.
