I've been using this for eons: https://play.google.com/store/apps/details?id=com.dynamicg.timerecording.pro https://play.google.com/store/apps/details?id=com.dynamicg.t... There's a feature limited free version. Lots of options to track times, jobs, breaks, options for how to deal with day roll over, etc. Unfortunatly Google forced them to break/disable the location tracking feature (despite that it was only doing using the information on-device) - which was super handy to 'clock in/clock out' when arriving at a site.. There's no server, but several backup options to some services or on-device storage.
