Some great features include: • Complete, copy or review timecards • Save default timecard as a favourite • Add timecard entries offline and submit when connectivity restored • Simple text search to find projects without memorizing project codes • Two-way synchronisation keeps GBS and MobileTime up to date – giving the same information on both the App and GBS • Approvers can action timecard approval notifications from their mobile device • MobileTime enforces existing GBS time entry controls, such as project and task transaction restrictions and minimum/maximum timecard hours • and delegation rules created in GBS for timecard approvals will be supported
