I use PC On/Off Time for Windows. It reads the system's boot/shutdown events from the system log and displays them in a nice GUI:
As a side note, I wrote a PowerShell script (Windows only) that does the same thing, but without GUI.
Is there a similar tool for Linux? It should
- Show daily uptime intervals and daily total
- Consider suspend/wake up as well as boot/shutdown
- Work nicely with sessions that span over midnight
- A GUI would be nice to have, but textual output is ok
- Open Source
I don't need the network feature. Local machine only.
