Encountering errors from test_czml_ground_station and test_czml_add_orbit #821

OrbitalMechanic · 2019-08-24T00:23:43Z

I'm running poliastro ver. 0.13.0 on an iMacPro running Mac OS X ver. 10.14.6 under Python 3.7.3. In running the test,

python -c "import poliastro.testing; poliastro.testing.test()

I get error messages concerning test_czml_add_orbit and test_ground_station. I'm testing poliastro with the setup.cfg file in the anaconda3 directory disabled (i.e., renamed so as not to be used). czml3 was installed.

The output from the test is contained in the attached file.

Please advise.

Sam Dupree.

Thanks for the report! It seems that these tests are timezone-dependent, which is most likely a bug. We'll investigate.

@Sedictious do you want to try and fix this one?

Oh no, time-zones again?
I'll check once I get back home, any idea what might be causing this @Juanlu001?

On a second thought, could we dynamically generate some tests on-spot (perhaps by regex matching and adding the system time to the date string)?

I am sure we are converting timezone-unaware dates to timezone aware in some incorrect way somewhere, in Python it's a bit tricky to get it right.

Culprit:

>>> from czml3.types import format_datetime_like
>>> from astropy import time
>>> t = time.Time("2013-03-18 12:00", scale="utc")
>>> t
<Time object: scale='utc' format='iso' value=2013-03-18 12:00:00.000>
>>> format_datetime_like(t)
'2013-03-18T12:00:00Z'
>>> format_datetime_like(t.datetime)
'2013-03-18T10:00:00Z'

Therefore, it turns out this is a problem in poliastro and not in czml3. Fixing it in #783 and closing this.

OrbitalMechanic · 2019-10-14T01:40:22Z

Has poliastro been updated so that it can be installed using pip? Sam Dupree.
