How to Increase build agent execution time? (VSTS)

When running long running tests (perhaps UI tests with Selenium)
I got this error:

The job running on agent xAgentNamex has exceeded the maximum execution time of 01:00:00.

The default timeout for VSTS Agent is 60 minutes.
The solution was to increase Build job timeout in minutes, under settings of build definition in the VSTS dashboard.
