Can i gift a friend a month of game time if hes on a different realm?

If i wanted to send a month of game time to a friend in Argentina, is that possible and how would i do it?

It looks like the shop has BattleTag or email address options for game time gifting. Realm should not matter.

Regarding regions, here’s the FAQ: Blizzard Support - Buying Gifts for Friends in Another Region (battle.net)

Of note:

real question is, am i the friend?

I have no idea what the answer is, but I’m assuming you meant region rather than realm.
