ProjectLink 9.1: Activity/Action Item. task duration

Hello

Our current system is so that only the date appear in the estimated start/finish actual start/finish

We looked in the preference manager to see if we could change this to also have date & time so we can record if a task got completed in 2 hours. At the moment it is based on days. which is ok for action/activities which last several weeks but not for those little ones

Does anyone know if this is something which can be changed somehow, without going into customization of course.

Thank you

Best regards
