   The comparison of DataTypes is done in Arrow C++ and for timestamps it is comparing the exact timezone string (it is saved as a string) as you have mentioned.
   
   To do a logical comparison of timezones one should probably use a dedicated library for that. In Python you could try with:
   
   ```python
   >>> import pytz
   >>> pytz.timezone(pa.timestamp("us", "UTC").tz)
   <UTC>
   >>> pytz.timezone(pa.timestamp("us", "utc").tz)
   <UTC>
   >>> pytz.timezone(pa.timestamp("us", "utc").tz) == pytz.timezone(pa.timestamp("us", "UTC").tz)
   ```
   
   and then separately compare the timestamp unit:
   
   ```python
   >>> pa.timestamp("us", "utc").unit == pa.timestamp("us", "UTC").unit
   True
   ```
