Starting today, the precision for the
created_at timestamp returned by the Get Users endpoint will be updated to seconds. Previously, this value could have included a higher precision with fractional second digits. RFC3339 is still the format to expect.
A higher precision cannot always be provided, so the precision is being updated to values that can be guaranteed (i.e. to the second).
This change may affect any developer who was expecting a higher precision than seconds (e.g. fractions of seconds). Given this was not always a guarantee, we believe the impact to be low.
Code that expects or was written to interpret fractions of seconds can be eliminated if there is a negative impact to your application.
