How does it work with time changes on a bus?

Question

since we just changed from Daylight savings time to
standard time
how does work when suppose you were at a bus
station and the bus was to arrive at 2:00am (lets say the time
we have to change the clock back a hour
what time will 2am bus arrive then? at 1:00am?
then a similar question
(when we change back to DST
the train is due at 2:00am but the clock goes forward
an hour does that mean I missed the bus
or the 2:00am train become a 3:00am bus?
