Depending on your job, your employer may be legally required to track your time. Any "non-exempt" employee has to be hourly, and has to be time tracked, per FLSA. Whether programmers fit in the "exempt" category (administrative, executive, and professional) is questionable, though the consensus seems to be that they do. Other jobs that are less "creative" may not qualify, and thus would have to be hourly and thus tracked. Unless the employer were ignoring the law, which happens.
