My boyfriend and I are arguing about this one: what does -ish mean after a time?
If I say 8-ish, will I be there at 8? Will I be there at 7:50? 8:20? Do I have a specific time in mind?

Мне понравился такой ответ:

If one of you is a Filipino, it means 10.

If one is prior military, it means +\- 5 minutes.

If you are a person that is on time normally, it is +\- 15 minutes.

If you are both late all the time, it is +\- 30 minutes.

and if you are a black guy, you never even think of those numbers above because you always show up on CPT.

думаю адекватный перевод "около 1:30"
или если угодно "в районе 1:30"
сохраняет примерно ту же свободу интерпретации читателем - в меру его испорченности ;)
