Not necessarily - A GM could easily handwave the time:
"So you guys dodge the last TIE and make the jump to hyperspace."
"Cool! How long will it take us to get to Ryloth?"
"Oh, about 60 hours"
"Fantastic, I put 30 of that into working on my Bithin' Armor"
*player makes note on sheet*
"Right, so screen wipe to you guys dropping out of Hyperspace in high orbit above Ryloth. . . .”
Giving them free time now is like giving them free money, so you’ve got to account for that in your plans. Otherwise, they quickly wind up with their super-ultra-duper-bithin-armor that is better than anything else in the Universe, and you have no way to hurt them short of having Boba Fett sneak up and steal it from them.
I’m just saying that the time you give them is now a significant factor that has to be taken into account, whereas before you could just handwave the time for pure PLOT reasons without having to worry about what might have happened during that time.
