Distance and timezone issue??

So:

there’s this guy with whom I have been talking to a lot since march. We really like each other, we would even date, but we dont since we are in different countries. We dont text much, but we talk once a week from 12 (00:00) to 5am (kind of compensates the fact that its once a week i guess?). We talk at this hour cuz thats when he is usually free, and since the time zones are the same, i dont mind. But I’ll soon be moving to another country, where it’ll be +5 hours. Therefore while its 12 at his place, itll 5am at mine. PROBLEM: should I just wake up once a week at 5am to talk to him? Should I tell him? Im considering lying about the time difference and hoping he wont check it out in the internet himself, cuz I dont want him to feel bad. But he really doesnt have any other time, and if i tell him about the time difference, in sure he wouldnt allow me to do that to myself.
