Some others like me are finding out that Marketo system time seemed to not adjust automatically with the daylight savings time change in the U.S. this past weekend.
The system should do this automatically AND not impact our scheduled activities.
Manually adjusting your time zone in your Marketo profile changes the time on all of your scheduled reports, emails, nurture streams, etc. -- which means they are off by 1 hour until you go re-set them all.
And then you may have to do it all over again several months later when daylight savings time happens again.
Please let me know if I am missing something in the Admin area that would fix / solve this.
