Why is my Rules Component not being scheduled accurately?

Question

My aim is to send an email to new students at certain weeks after admission. E.g week 28, week 32, week 45.

I set up components with action to send email.

I configured a rule with event: after saving new content type(student).

The content type has a field - date of admission.

I scheduled component evaluation based on the offset of 'date of admission'.

So for example:

Date of admission: 02/03/13 (March 2nd 2013)

Offset: 224 days

However when the rule is triggered and I go to admin/config/workflow/rules/schedule, I noticed that the scheduled date is 16/10/13 rather than 12/10/13.

Please how can I resolve this?

Answer 1

When scheduling a Rules Component, you specify a value within Scheduled evaluation date. One of the options to do so, is to specify Relative dates like "+1 day", as mentioned within the Rules UI:

... any other values in GMT known by the PHP strtotime() function (like "+1 day")

As per your "offset = 224 days", I'm assuming you used a value like "+224 days".

However since you want to schedule the Rules Component a certain number of weeks after admission (like "week 28, week 32, week 45."), try to specify Relative dates like "+28 weeks", "+32 weeks", "+45 weeks". That might help for the Rules Scheduler to show a more accurate date.
