Time spend in Nursery.

[Grular]

Hi,
I hope i'm writting on the right topic/section.
It's not really a game suggestions but i think this thread could stay here.

So i saw somethink that trouble me when i do Nursery solo.
I'm iss enchanteur so i have plenty of self-buff and i'm always astonashing about time spend in Nursery. I explain myself with an exemple.

I come in Nursery and, juste before talking to Tie i use a Vitality potion maintening 30min.
So Just after i speak to Tie and the timer start ( 30min and my vita potion has 29min59 sec left).
But, amazaingly, when i still have 1m30 in instance i loose my potion. It's the same with buff.
So does buff/potion/etc really long 30 minutes or are they a bit shorter ?
But it's most certainely Nursery who has a time disturbing. Nursery long more than 30 minutes ( even if it's write 30 mins).

Sorry for my crappy english.
