The Details: For the guy who always needs to know the time and date, this is a gift he'll love. It's a highly accurate atomic clock that tells the time, date, humidity, temperature, phase of the moon, and day of the week in bright (some say TOO bright) numbers. The time is synced to the NIST-F1 atomic clock for maximum timekeeping precision.
But it's also a phone charger, so he can plug his phone in to keep it charged all night long. The clock runs on AC power (via the wall socket), but it comes with AAA batteries to ensure it stays on even if the power goes out.
Price: $50 isn't too high a price to pay for an alarm clock that charges your phone and gives you accurate timekeeping. It's a gift he'll use for years to come!
