Description

When printing TimestampArray in pyarrow the timezone information is ignored by PrettyPrint (_str_  calls to_string() in array.pxi).

import pyarrow as pa

a = pa.array([0], pa.timestamp('s', tz='+02:00'))

print(a) # representation not correct?
# <pyarrow.lib.TimestampArray object at 0x7f834c7cb9a8>
# [
#  1970-01-01 00:00:00
# ]
