This extension allows you to choose from a large selection of in-game clocks and display them in the main Pardus menu (so they are visible at all times).
You can customise the font size for the clocks as well as the location across the menu where they will appear. You can also change which clocks show for each universe (via the Options link from the Extensions tab in Chrome).
The more clocks you choose to enable, the more width is required to display them all properly (so you may need to be selective about your choice of clocks).
All clocks will sync with the Pardus server time - so even if your local computer time is not accurate, the clocks should still reflect correct timings.
