Hello Eric,
I know this is not elegant, but I'd do it this way:
---8<---
alice :task => 'prep package', :timers =>
'${r:Time.at(wi.fields['contract_date']) - 5.days}: reminder'
--->8---
(note I've used ActiveSupport #days in this example).

That would require a good temporal language in ruote.
Others have implemented such languages in Ruby, I was thinking people would
simply use the one they prefer in their participants (or in ${r:x} constructs).
https://github.com/mojombo/chronic
https://github.com/bokmann/business_time
https://github.com/dcparker/temporals
...
One thing I could do is checking whether the participant class responds to a
#timers method and call it if present. This is currently only implemented for
timeouts (via a #rtimeout method (since JRuby forces a #timeout method on every
object)).
We currently only have
---8<---
class MyParticipant
include Ruote::LocalParticipant
def rtimeout(workitem)
(Time.at(workitem.fields['contract_date']) + 10.days).to_s
end
end
--->8---
we could thus have also
---8<---
class MyParticipant
include Ruote::LocalParticipant
def timers(workitem)
(Time.at(workitem.fields['contract_date']) - 5.days).to_s + ': ' +
'reminder'
end
end
--->8---
Not sure if my answer makes sense, kind regards,
