This is a bug in ticker that will be fixed in the next bugfix
release. If you want to fix it yourself now, edit
matplotlib/ticker.py and add SEC_PER_MIN to the list of things
imported from the dates module. Ie,
from dates import EpochConverter, SEC_PER_HOUR, SEC_PER_DAY, SEC_PER_WEEK, \
SEC_PER_MIN

Thanks John,
everything works right now, except for fact that I need to "clear" it on every iteration ...
and the line where I try to clear the previous figure ("ax.clear()") is giving me troubles.
Thanks in advance!
