Change the Time Zone to Mountain Time

Countdown Timer uses the timezone settings for the blog: https://en.blog.wordpress.com/2010/03/16/set-your-blogs-timezone-by-city/

my blog has timezone UTC+1

your plug-in always set CEST

@andrea.petrucci.1975:

The plugin itself uses the timezone set my WordPress. How are you determining that CEST is being used?

if in event setting i put “01-08-2014” plugin change this in “Fri, 01 Aug 2014 00:00:00 CEST” and i have a 13 hours offset with UTC+1
