NLT is used to express a deadline: it tells you the latest time something must be done. The standard phrase that NLT stands for is “No later than,” which directly conveys that you must complete or submit by the specified time. For example, “Submit the report NLT 1700 hours Friday” means the deadline is 5:00 PM Friday, and late submissions aren’t accepted after that moment. The other phrases aren’t used to indicate a deadline in official communications: they either sound awkward or imply a different idea (for instance, a duration rather than a cutoff time, or they’re not a recognized construction).
