Non-Course Schedule items should not have times increment by half-hours.

[klairecodes]

When creating Non-Course Schedule items, the select-able time ranges should be in increments of 5 (or at least 15) minutes, not half hours. Having them change by halves is inconvenient for the current structure of RIT's courses, as well as does not reflect the more specific times that non-courses could start and end at.
