[Numpy-discussion] UTC-based datetime64

Hi, We've found that NumPy uses the local TZ for printing datetime64 timestamps: In [22]: t = datetime.utcnow() In [23]: print t 2015-08-26 11:52:10.662745 In [24]: np.array([t], dtype="datetime64[s]") Out[24]: array(['2015-08-26T13:52:10+0200'], dtype='datetime64[s]') Googling for a way to print UTC out of the box, the best thing I could find is: In [40]: [str(i.item()) for i in np.array([t], dtype="datetime64[s]")] Out[40]: ['2015-08-26 11:52:10'] Now, is there a better way to specify that I want the datetimes printed always in UTC?
