Adding color to today cell in timeline is difficult

I’m using this:

		days:  new Date(),               
		zones: "fullday",       // marks the entire day
		css:   "gray_section"   // the applied css style

to color today date in timeline, but it doesn’t work, more examples are need to use the scheduler, it’s diffucult to use some of it’s features sometimes.

the code seems working as expected in our samples
