Places of power time lag?

[Real Vincent]

i am not even sure if this is the right place to post, as it seems like a bug which appears only at nutaku.
but i observed this a few times now.
i start places of power on both hentaiheroes account and haremheroes account (nutaku) at about the same time. all with enough girls to do in 7 hours.
a few hours later i log back in, and there is a big difference.

just right now, for example:
time remaining on hentaiheroes: 4h 22min
time remaining on haremheroes: 5h 5min

one of the timers is off. probably the one at nutaku is too slow, but i am not sure.
