Timesheets are the lifeblood of our company; they have a direct impact on revenues. If you help a colleague on a project, your time should be recorded on this project's timesheet as well. It's part of the job to search for information. A customer can't expect you to know everything on the spot. These hours should also be billable. Make it a habit to record timesheets every day. Even small tasks like answering an email should be recorded and rounded up to a quarter of an hour.
