It's easy to lose track of time while playing with Opencode. To help with this, it would be useful to display a clock in the bottom line of the sidebar on the same line as the name of the program and the version are displayed aligned to the right edge of this line. The clock can use a 24-hour time format. It needn't be accurate to the second, updating it every 10 or 15 seconds would probably suffice to keep the displayed time at least accurate to the minute.
A command palette item in the System group, named "Show sidebar clock" or "Hide sidebar clock" depending upon its current state, can be used to to enable or disable the clock, with its state persisted to kv.json, similarly to the several similar Hide/Show items that already exist in the command palette.
