Type- Can be Global, Assigned or User

This system option determines where the Start and End Time populate from when scheduling
a job. The choices are Job Time Slot Start & End Times or First Job Line Start &
End Times. In most cases, these are the same, but some users manually edit line times
after scheduling with a generic time slot.
