Hi,
thanks for armory sync plugin.
For the date parsing bug, both installation of Joomla 2.5 and 3.x are standard.
After verification, the french language in administration is the cause of error “DateTime::__construct(): Failed to parse time string (25/03/14 18:27) at position 0 (2): Unexpected character .”
So i turn on the french language on the site and english language for the admin of joomla.
With this configuration, that component work perfectly.
Thank you.
