Timestamp change 6.11.2018
Significant changes in API timestamps
The road and marine API’s of Digitraffic were migrated to AWS cloud service on 6.11.2018. Alongside the migration the timestamp format used by the API’s was significantly changed.
The communication regarding the change was insufficient and several API users were not prepared for the change. These kind of API changes are rare and the Finnish Transport Agency (FTA) tries to avoid them. The FTA has taken action to ensure adequate communications regarding API changes in the future. The FTA is sorry for any inconvinience caused for the API users.

In application development the timestamps should be handled with libraries or functions spesifically designed for timestamp handling. Using timestamps with other methodts, e.g. with functions designed for string handling is prone to errors.
