Problem with timezone scheduler

I use timeline scheduler.
I have a windows computer and when I send with ajax the ev object,

the start date has this this format

Mon May 21 2018 00:00:00 GMT+0200 (ORA LEGALE Europa Occidentale)

I am Italian.
The problem is the string (ORA LEGALE Europa Occidentale) that cause me error in format date…
How I can change this behavious

When Scheduler is using a standalone SchedulerDataSource, then the timezone option needs to be defined to the schema option like that:
Thus the source knows how to treat the received data.
