If I let the plugin go standard like that:

"Options": {
"Duration the vote will be open": 210,
"Required vote percentage": 60.0,
"Time the vote will open": 18.0,
"Time to set on successful vote": 7.0

the second vote time in the middle of the night takes much too long and is still open after 7 am has passed. This makes no sense.
I tried to change "Duration the vote will be open" to 180 to shorten this to get a chance that the vote is finished before 7 am.
But then the first vote didn't start at 18 pm anymore but later and was still open after 19 pm.
The only thing that kinda works for me is when I put the "Time to set on successful vote" to 8 so that the last vote will definitely be finished.
But there has to be another way to configure this the way I need right?
How can I ensure that the last vote finished before 7 am?
Or can you please tell me at least how to shorten the voting time for that without having the issue that the votes won't start at the right time then!
Thank you.

So after returning to my former setting like: 
"Options": {
"Duration the vote will be open": 210,
"Required vote percentage": 60.0,
"Time the vote will open": 18.0,
"Time to set on successful vote": 8.0

which worked fine for me now the the first vote takes longer than normal. It starts at 18 but doesnt end at 19 as it used to.
This plugin is kinda messed up somehow with time.
What shall I do? I need help please!

Just to let you see what I mean.

AAnd as you can see now the second vote is ending at 5 am, it used to end some minutes before 7 am. Why did this happen? I just changed duration the vote will be open and the time once and changed it all back to what it was before and now it's all messed up.
Btw, why is there no config time setting for the second vote in the middle of the night?
I would be really glad if I could just set this plugin the way it makes sense to me or at least get it to work like it did before I changed something. :)
