Is there an API for Finesse IP Phone Agent?

Regarding the finesse phone book limitation below:The system supports a total of 50,000 contacts. The total number of contacts per agent across all phone books is limited to 1500. Is the 1500 restriction imposed by the database, the API or the gadget...

The call history gadget in finesse shows the history in server time (confusing to those on East Coast to add 2 hours from the Mountain Time servers). Is there any way to align this to the timezone the agent is working in?
