opencart 2.0 securepay integration fingerprint error due to timestamp

Using opencart 2.0 integrated into a joomla website as mijoshop, www.mijosoft.com. have installed the securepay iframe module for opencart 2.0. We are getting a fingerprint error each day from about 10am to 12 noon AEST time. From talking to securepay it would be caused from a timestamp error. We need to have their module modified to fix this error.
