Try printing mylist. Then you'll know why - operand doesn't work.
You're creating a nested tuple.
I'd recommend changing the original script to something like::
seconds = []
[snip]
# Convert the date format to the seconds since epoch
for i in xrange( len(dates) ):
thissecond = parseDate(dates[i][1])
seconds.append(thissecond)
or if you want to stick with tuple::
seconds = ()
[snip]
# Convert the date format to the seconds since epoch
for i in xrange( len(dates) ):
thissecond = parseDate(dates[i][1])
seconds += (thissecond, )
