Run following to update DB:

ALTER TABLE projects ADD COLUMN created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;
ALTER TABLE projects ADD COLUMN updated_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;

ALTER TABLE charts ADD COLUMN created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;
ALTER TABLE charts ADD COLUMN updated_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;

ALTER TABLE reports ADD COLUMN created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;
ALTER TABLE reports ADD COLUMN updated_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;

ALTER TABLE report_like ADD COLUMN created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;
ALTER TABLE project_like ADD COLUMN created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;

ZEN-266 add created_time column to projects and reports

Also add created_time to likes to calculate "trending"
