#get_data_for_time_span ⇒ Object

Set up instance variables for render templates or returned json

params:  @t1:      time-inverval start
         @t2:      time-inverval end
         @inc:     incremental update?  One of: nil, 'lo', 'hi'

creates: @rsrcs    ordered resource list
         @blockss: lists of use-blocks, keyed by resource

end

#json_adjustments ⇒ Object

Always send starttime/endtime attributes as Integer values (UTC) – they are used to size and place the use_blocks. Timezone is configured separately in the ZTime* classes (config/resource_schedule.yml).
