I believe that it is effected by the equinox. Because the sun appears to move faster across our sky's in the winter or slower in the summer this might be the main cause of why a solar eclipse might differ in time. The moons distance from the earth also differs and this may also affect the rate of time that a lunar or solar eclipse occurs.
The average duration of a total solar eclipse is around 7.5 minutes, but it can vary from a few seconds to a maximum of about 7.5 minutes depending on the specific path and circumstances of the eclipse.

The duration of Full Eclipse is 1.55 hours.
The duration of Days of Eclipse is 2.22 hours.
The duration of Saigon Eclipse is 1.5 hours.
The average duration of a total solar eclipse is around 7.5 minutes, but it can vary from a few seconds to a maximum of about 7.5 minutes depending on the specific path and circumstances of the eclipse.
The total time of the eclipse was about 3.5 hours. However, the duration of the eclipse was 6 minutes 39 seconds if you were standing still along the centerline of the path of totality.
A total solar eclipse occurs approximately every 18 months somewhere on Earth. The duration of a total solar eclipse at any particular location is typically a few minutes.
The longest duration of a total eclipse is 7 minutes 29 seconds.

There was no solar eclipse in December, 1992. So, I guess the answer would be "zero point zero seconds". http://eclipse.gsfc.nasa.gov/SEgoogle/SEgoogle1981.html
