Where 48 hours shows up
Forty-eight hours is two days on the clock, which is not the same thing as two business days — the phrase a support policy or returns window more often intends. Counted literally, something logged at 4pm on a Friday falls due at 4pm on Sunday; counted in working days it falls due Tuesday. When a deadline matters, the question worth asking is whether the 48 runs from a timestamp or from the start of the next business day, because the two can be days apart.
