define SLA for an Issue

Submitted by suminda on 2012-10-07

hi,

Can i know how to set SLA (service level agreement) for a particular issue with respective to login time automatically,
ex: if my SLA time starts at 8 am to 6 pm for a particular issue type with a SLA period of 15 Hours target,
when i raised an issue at 8am today, the system should trigger expected resolution time as 1 pm of following working day,

regards,
Suminda,

+1. We can say automatic assignment of some fields.
Eg: If x field is a then y field is b
if x field is a then y field is x+5(for dates)

or coding detailed sla system.
