Yes, it can. The K3 commands involved are K31; MN073; DS; SWT11; UP; or DN; SWT12; UP; or DN; SWT13; UP; or DN; and MN255;
Recent versions of Windows (certainly XP and beyond) include an NTP client that can synchronize with one of several NTP servers. You right click the time in the status bar, choose "Adjust Date/Time", select the "Internet Time" tab, optionally provide an alternate NTP server and punch the "update now" button. No special NTP client code is required to get to the accuracy necessary for this sort of task.
