Add a flag to suppress the standard view on time fields.

[travisturner]

Description

time fields automatically create/populate a standard view which represents all setbits with no time value taken into consideration (like a set field). It's possible that a user wouldn't need that data. In that case, we could give the user the option to suppress that view (i.e. improve write performance and reduce storage requirements).

Success criteria (What criteria will consider this ticket closeable?)

I guess this would mean modifying OptFieldTypeTime() to include this additional option. Note that that would be an API change. We could also provide a separate option, but that may be confusing.
