Extends the deadline when opened on weekends
- When it's late in the week, primarily Friday and Saturday, QA issues will close before some Engineers have had a chance to even look at the issue
- This extends the deadline for issues opened on those days from 24 to 48 hours, increasing the chance an Engineer should work on any items in a QA task
