For your scenario you can add two tasks: Dept A, Dept B. You can set the duration for each to 0 if you don't have any idea of how long you want to work for, you just want it to record.
Start the timer, the top task is the active one. When you want to switch, just drag & drop the second task to the top (you can play around with the sorting order). Mark the tasks as complete at the end of the day. By default tasks will be "cleared" when you mark them as complete (you can turn this off in the settings). All it means is that you can go to your "Cleared" list and it will show you all the past completed items - just so they don't clutter your main lists. It will show you the date completed and how much time was spent.
I'm not sure if this is exactly what you're looking for, but I recently found the app Do Now, which allows you to have multiple countdown timers.
Not exactly what you're looking for but this https://play.google.com/store/apps/details?id=com.slamtastic.donow.app&hl=en has helped me a lot.
First you tell the app all the things you want to do today and how long you think each is going to take. It will then remind you when it's time to move on to the next task, giving you the option to complete the task and start the next one or snooze the reminder, if you're not finished yet (unfortunately, this first notification won't repeat unless you tell it to snooze - pretty much the only thing I don't like about this app).
Do spend a dollar (or whatever it is in your currency) on an upgrade, it's absolutely worth it for the extra features.
It's only on Android for now but I've made something like this: https://play.google.com/store/apps/details?id=com.slamtastic.donow.app
Stats are a weak point right now but I started with calculating what you just said. i.e 2hrs 15mins time spent vs 2hrs 30 mins planned
Can you tell me what you think of mine? https://play.google.com/store/apps/details?id=com.slamtastic.donow.app
It's more geared for pomodoro-style of doing things so it's not an organization heavy todo list.
Not sure how you want the clocking out part to be handled but you can try

Make a task named "work" with the duration you'd like (i.e 2 hours) and a "break" task after it then when you're ready to start, hit play. You can save this combo as a routine and have the tasks automatically added at a certain time. You can also set it on auto-repeat so when a task finishes, it gets added back to the bottom of the list.
Do Now - Focused Timeboxing. Flexible and powerful tool for managing time and not just tasks or just intervals unlike all other apps.
The gist: Focus and get things done. From applying timeboxing/pomodoro-style techniques to interval training for workouts and other similarly structured time blocks. As one of my users described it, the idea is to have "life on autopilot without ever looking at my phone."
This app is based around the idea of timeboxing and simplifying the todo list. I personally get overwhelmed with the organization heavy apps and feel like I spend more time organizing my tasks rather than doing them so this is for all others like myself. Focusing on time rather then the tasks subconciously makes me prioritize and helps me focus on what I need to do right now. Using an "Unplanned" list as a brain bump lets me forget about the things that are not a priority now/today. Having saved lists of "Routines" that I can load into any other list and schedule to move to my "Planned" list at repeating intervals gives my brain a rest. The timing aspects allow the app to also be used as an interval manager and not just purely a task management app. I also designed it to be low impact on battery life unlike a lot of other timing based apps. I don't think there are any other apps that have all these combinations of features in a flow that makes sense. And I'm adding more and more themes to choose from.
I'd love to hear what you think!
Sort of a different take on the todo list but you can try https://play.google.com/store/apps/details?id=com.slamtastic.donow.app&hl=en
I made this Android app which does the whole timing thing but not meant for intense organization like Todoist. A user made this Zapier Recipe though which syncs Todoist with Google Tasks which syncs with my app.
okay, found it
