KB46207: Distribution Services schedules modified using the ALTER SCHEDULE Command Manager outline are triggering on incorrect days MicroStrategy 9.x

SYMPTOM:
 
Distribution Services schedules edited using the ALTER SCHEDULE Command Manager outline are triggering on incorrect days in Strategy 9.x. This issue persists even after an Intelligence Server restart.
 
For example, a Distribution Services schedule configured to only trigger on Mondays at 6 AM will trigger at 6 AM every day of the week after being edited using the ALTER SCHEDULE Command Manager outline.
 
STEPS TO REPRODUCE:
 
Using Strategy Tutorial 9.x:
1. Create a schedule named "Weekly Every Monday 6am".
2. Create a subscription that uses the "Weekly Every Monday 6am" schedule.
3. Use the following Command Manager command to change the schedule start date to a future date:

ALTER SCHEDULE "Weekly Every Monday 6am" STARTDATE 01/01/2020;

4. Use the following Command Manager command to change the schedule start date to a previous date:

ALTER SCHEDULE "Weekly Every Monday 6am" STARTDATE 01/01/2014;

5. Wait until 6am the next day. The schedule will be triggered even if it is not Monday.
