Implement trait ToSql for Date and Time

[SciMind2460]

I have implemented a ToSql that can be used in rusqlite for SQL data. This can be implemented like this:

conn.execute("INSERT INTO users (name, age, date_of_birth) VALUES (?, ?, ?)", (person.name, person.age, person.date_of_birth))

And also Time, as:

conn.execute("INSERT INTO items (time) VALUES (?)", (item.time))
