The "time-vision" bit was seen in the late 1990's "The Kingdom" miniseries (various future Supermen are using it to pierce the time barrier to examine some specific event...).
I never read THE KINGDOM, however, if they were in the timestream when they used their "time vision," this isn't a separate power, but merely how time travel functions.
Pre-Crisis, the reason the Legion of Super-Heroes' Metropolis needed a "Time Beacon" such as the one that was present on the Metropolis Institute of Time, was to act like a "lighthouse" for Time-Travellers to prevent them from getting lost in the time stream. Without a Time Beacon, it is assumed that only beings with powerful personal senses, like Superboy, dare attempt to cross the time barrier on their own.
