I'm about Firefox's plugin.
When I want add time to some task, I use your insturtions and try write time as described in instructions in russian - "сегодня в 13".
But your plugin alert a "неверная дата" (wrong date in english) and not accept any variants e.g. "26 авг в 13" "26 авг в 13:00" ...
Only I write in english as "today at 1pm" it accept.
Please correct your plugin or change instructions on Russian - "date and time accepted if it writen in English language only"
