Geocentric Phases of the 2012 Transit of Venus:
                            Contact I      22:09:38        41°
                            Contact II     22:27:34        38°
                            Greatest       01:29:36       345°
                            Contact III    04:31:39       293°
                            Contact IV     04:49:35       290°

Table 1 gives the geocentric times of major events during the transit. 
Greatest transit is the instant when Venus passes closest to the Sun's center (i.e. - minimum separation). 

Note that these times are for an observer at Earth's center.
The actual contact times for any given observer may differ by up to ±7 minutes. 
This is due to effects of parallax since Venus's 58 arc-second diameter disk may be shifted up to 30 arc-seconds from its geocentric coordinates  depending on the observer's exact position on Earth. Table 4 provides similar predictions for a number of cities around the world. Bucharest* -- - -- - -- - 07:37:40 20 07:55:14 23
