Abstract
A method and apparatus are provided for performing synchronization of a time clock maintained by a computer system based on the network connection modes of the computer system. The technique allows the time clock of the computer system to be synchronized at the earliest opportunity that will not result in a disruption or inconvenience to the user. When synchronization of the time clock is required, and the computer system does not already have an active network connection, the computer system queries a configuration database to determine its default network connection mode. If the default connection mode is potentially user disruptive (e.g., use of a dial out modem is required), synchronization of the time clock is not performed until an active network connection has been established. If the default connection mode is not likely to be user-disruptive (e.g., doesn't require a modem connection), then a network connection is immediately established to synchronize the time clock.
