The Local Time at Ascending Node (LTAN) is the local time at which the spacecraft passes the Venusian equator on the ascending branch.  For the first orbit (2144, on 4 March 2012), the LTAN is 23:47, for the last orbit (2171, on 31 March 2012), it is 02:42.

As on Earth, standard time zones are defined by geometrically subdividing Venus' spheroid into 24 wedge-shaped sections bordered by meridians, each 15° longitude apart. The local time in neighboring zones would differ by one Venus hour, or 1/24th of a Venus day. The variation in the position of the Sun from one end of the zone to the other (East vs. West) would be 1/24th of the sky.
