Internet Delays

We emphasize that the displayed time is not corrected for Internet delays between our server and your computer. Under favourable Internet conditions, we have observed the above time display to lag NRC clocks by 0 to 2 seconds when accessed from our workstations in Ottawa, Canada. Longer delays could be expected under less favourable Internet conditions.
