The API was updated to fix a bug that prevented Employee swap from working correctly.
We have added the ability for routes that return times to accept a timezone. When you do not pass in a timezone it will default to Eastern Standard Time.
If the parameter is supplied the time will be sent back with the requested in timezone applied.
To view a list of available time zones please call https://api.connectionsonline.net/v4/timezones
For more information on the routes that accept this new parameter please see these sections in the help documentation: Comment, Dialog, Individual, Metric, Project, Task, and TrendValue.
