The way day/date attributes are used has changed.  Recall how day/date with time attributes:

Here the day/date act like a guard over the time. Hence the time is not considered until the day/date is free.

task t1      # run on Monday @ 10:00
  day monday
  time 10:00
task t1   # run on Monday @ 10:00
   date 05.08.2019
   time 10:00

In ecflow 4.0 the definition below can produce unexpected runs.

ecflow 4.0 each time attributes is treated individually.

Here time was set free on Sunday.

ecflow 4.0
...
family f1
   day monday
   task t1
      time 10:00  # runs Monday@00:00 and Monday@10.00

In ecflow 4.0 the day/date act like a guard over any other time attribute.

Hence the time is not considered until the day is free

ecflow 5.0
...
family f1
   day monday
   task t1
      time 10:00  # runs on Monday@10.00

The behaviour in ecflow 4.0 happens because the time attribute are treated individually.

Here the time 10:00, was set free on Sunday. 

(when time attributes are set free, they stay free, until re-queue.)

ecflow 4.0
...
family f1
   day monday
   task t1
      time 10:00  # runs Monday an midnight and Monday at 10.00
ecflow 4.0
...
family f1
   time 10:00   # time set free on Sunday. Stays free until re-queue
   task t1
     day monday # runs Monday an midnight and Monday at 10.00

In ecflow 5.0, The day acts like a guard over the time.

The time is not set free, until Monday is free.

Hence this produces the expected results.

ecflow 5.0
...
family t1
  day monday
  task t1
    time 10:00 # run on Monday @ 10:00
ecflow 5.0
...
family f1
   time 10:00   # time set free on Sunday. Stays free until re-queue
   task t1
     day monday # runs Monday an midnight and Monday at 10.00

 Hence in ecflow 5.0,  in the following definition, the task will never run:

family f1
   day monday
   task t1         # t1 will never run, cant be Monday and Tuesday at the same time
      day tuesday
