Paper revision exact deadline I am revising a paper submitted to IEEE TVT journal. I'm quite tight on time and trying to complete the paper revision by its deadline which is on Sep 10,2018 (Monday). 

Does anyone have a paper on TVT and know the exact meaning of deadline for this journal ? Is it on Sunday night or Monday night ?
Relax. Journal deadlines are not strict (unless they are for special issues with a set publication date). They're more intended to help keep the journal organized. Chances are you can go weeks past the deadline and nothing will happen, although if you wait months, your submission might be removed as dormant.

If you're still concerned, ask for a deadline extension. It's likely the journal will grant it.
