daylight saving error!

After the daylight saving appeared in my timezone (UTC - 5 Central times) my scheduler has the time error when i try to create a new event. Here is the screenshot.
I updated all the components up to date but the problem still happening?
Is there any otherway I can fix this problem?

sorry i forgot to include the screenshot on previous post

Please provide info about used browser and version of operation system

I use chrome for browser and script ver 4.0 standard

I mean OS is 7

Unfortunately I still can’t reconstruct the sample.
Is problem occurs in default samples of only for your app ? In second case - please provide any kind of sample or demo link where issue can be checked.
