Your POWr plugin may have a time-related element. Some POWr plugins that have time elements are Form Builder, Countdown Timer, Booking, and so forth.
Your POWr plugin's time zone is determined by your system at the time of set up. An example is if you set a Countdown Timer to count down to midnight December 12th, 2020 and you're in Pacific Standard Time. All your site visitors will have their views adjusted to correspond with your time zone; so for New York it's adjust three hours, Paris by nine hours, and so forth.
