What happens to an enchanted weapon in a warlock's/Eldritch Knight's dimensional pocket? Say you cast Magic Weapon on a non magic bonded/pact weapon, it becomes a +1 weapon up to an hour. You then have a 5 to 10 minute combat encounter leaving some 50 minutes left remaining on the enchanted weapon. You then pop said weapon into the warlock's/Eldritch Knight's dimension pocket.
Now, until whenever the next combat encounter happens (could be hours, days, weeks if you're lucky), will the weapon still be enchanted when re-summoning it. Is the dimensional space the bonded/pact weapon is stored in, keep it in a temporal stasis where once it's placed there enchantment and all effects , it remain that way till it is re-summoned.

It stops being magical because you (probably) stop concentrating on it.
Note that the spell requires that you concentrate on it for it to be active. If a combat encounter ends and you stop concentrating on it, the weapon stops being magical. You also cannot concentrate on the spell past the 1 hour limit, so the spell will be inactive when you re-summon it for a later fight.
It's possible for a character to continue concentrating on the spell at the end of an encounter. Then, if they begin a new combat encounter before the time is up and they haven't stopped concentrating, they could re-summon their weapon and the spell would still be active.
Extradimensional spaces generally don't freeze time.
Other instances of extradimensional spaces refer to the passage of time as if it progressed normally. For example, the Portable Hole states
Which does not draw a distinction between the passage of time inside and outside the space. Given that the class features don't address this, I think it's a safe bet that the extradimensional space for pact weapons don't freeze time either.
