RaspberryPi: Simple Time Server

Both my birdbox systems and my Portable (garden) PiCam need to know the time & date in order to properly time-stamp video clips and events.


Up until now I have relied upon an old HP Compaq D510 to help set the correct time, but I've finally got around to replacing this with a not quite so old Pi B v1 Rev1.


Although the D510 was quite economical, my Pi replacement should consume less than 5% of the power of its predecessor.

Real Time Clock for RaspberryPi

I bought a Real Time Clock module (RTC) about 6 months ago and I've only just taken it out of its anti-static bag.


With two potential projects in mind that may require an RTC, I opened the packet, wired it to my RaspberryPi and then....not a lot happened.


So I had to take a closer look and see what was causing the problem.

RaspberryPi: keeping time without the internet

The RaspberryPi does not have a real time clock (rtc) so normally requires an internet connection to reset the time and date from a time server.

 

For my BirdBox 2014 project I need to be able to time-stamp files & data, but it would not matter if the system time was a few minutes out either way, so I have been considering the options.


One popular solution is to connect a small rtc board to the RaspberryPi. These boards are small, low cost, and include a lithium backup battery.
