customize when an update of the data should be performed by the Scheduled Updates and at what intervals in a specified time-period.
One example is if you want to keep a file in memory between 06:30 and 19:00, but only update the data at 11:00 and 15:00.
To achieve this task you need to create three schedules with small overlap and long update intervals as follows:
Schedule 1: 06:30-11:10, update every 270 minutes (load at 06:30, update at 11:00)
Schedule 2: 11:00-15:10, update every 240 minutes (still in memory at 11:00, updates 15:00)
Schedule 3: 15:00-19:00, update every 250 minutes (still in memory at 15:00, unloads at 19:00 since the update is outside schedule).
