TimeLeft is a time synchronization utility. It can contact atomic clock servers and adjust time on your computer according to their data.

Right-click TimeLeft system tray icon to bring up the menu and select Tools|Synchronize Time to access Time Synchronization window:

When you click Start TimeLeft queries atomic time servers and displays the result in Proposed Time section. If there is considerable difference, click Apply (see TimeLeft Deluxe) to correct your system time automatically. Clicking a button next to Apply opens a drop-down menu that lets you apply hours, minutes and seconds or minutes and seconds only. To correct the system time manually, click System time button.

Note: If TimeLeft suggests applying the time which is one hour (or several undivided hours) different from your real time, this happens due to specific time zone or energy-saving time adjustment settings in your system. In this case you should use "Apply minutes and seconds only" feature.

Note:
TimeLeft uses Time Protocol (port 37) for synchronizing time.
Make sure this port is not closed by your ISP or firewall.

Atomic servers list can be edited: you can delete servers that are often inaccessible from your location and add your own (click Add and enter server address and description).
