DateTimeFromString off by one sec?

Hi,

I am using mx.DateTime to parse dates and times in ISO format. I have
noticed that DateTimeFromString seems to be off by one second if the
time string being parsed ends with :59

>>> mx.DateTime.Parser.DateTimeFromString('2008-05-06T19:30:09.59')
<mx.DateTime.DateTime object for '2008-05-06 19:30:09.58' at 651a8>

but

>>> mx.DateTime.Parser.DateTimeFromString('2008-05-06T19:30:09.58')
<mx.DateTime.DateTime object for '2008-05-06 19:30:09.58' at 8c250>

Adding formats=['iso', ] does not change the results. I am using
mx.DateTime 3.0 by the way.

Am I doing something wrong?

Thank you!
Francesco

It is not not off by a second, it's off by 1/100 of a second.

This looks a lot like a bug in the parser, since it starts to
parse the fraction with a 1/100 second offset starting at
x.59 onwards:

 >>> DateTimeFrom('2008-05-06 19:30:09.57')
<mx.DateTime.DateTime object for '2008-05-06 19:30:09.57' at 2b1e3bdb08c8>
