Latest list of frequencies posted at:

The 145.825 MHz packet is most common operating mode. It has its on/off 
days depending on crew activity and radio health.

Watch the amsat-bb for ARISS school contact announcements. For example 
there is a school contact scheduled for next week - direct with a school 
in Ohio. The 145.800 MHz downlink will be good copy over a lot of the 
northeast and parts of the midwest.

 > Why the [time] difference?

Often related to differences in using local time and UTC on different 
sites. I'd go with the amsat predictor for now.
