Observtion.__eq__ depends on identical encoding for time properties

[securedimensions]

Is this a bug?

Comparing observations with the same phenomenonTime but encoded differently results in not equals

Reproducing the error

import frost_sta_client as fsc

o1 = fsc.Observation(phenomenon_time='2024-04-17T12:00:00Z', ...)
o2 = fsc.Observation(phenomenon_time='2024-04-17T12:00:00.000+00:00', ...)

if o1 != o2:
    print("observations are not equal")
else:
    print("observations are equal")

Indeed. Time values are currently stored as Strings. They should be converted using an appropriate datetime class.
