US time: as each auction house lists it (PT = Pacific, ET = Eastern, CT = Central).
Central European time: an hour earlier for three or four weeks a year, when the US and Europe change their clocks on different dates.
"From": when the first cards close; cards with late bids close later.
Usually ends: my estimate for Fanatics Collect and Alt; for Goldin and Heritage, worked out from their extension rules.
