Arduino Timezone and DST Library

The Timezone library facilitates time zone conversions and automatic daylight saving (summer) time adjustments. This is accomplished by setting a Real Time Clock (RTC) to Universal Coordinated Time (UTC) and then converting UTC to the correct local time, whether it is daylight saving time (a.k.a. summer time) or standard time.

The Timezone library is designed to work in conjunction with the Arduino Time library at http://www.arduino.cc/playground/Code/Time. To download and use the Timezone library, including documentation and example sketches:

  • Go to https://github.com/JChristensen/Timezone/downloads and download the file in the compressed format of your choice (zip or tar.gz) to a convenient location on your PC.
  • Uncompress the downloaded file. This will result in a folder containing all the files for the library, that has a name similar to "JChristensen-Timezone-42e98a7".
  • Rename the folder to just "Timezone".
  • Copy the renamed folder to the Arduino sketchbook\libraries folder.
  • Read the ReadMe.txt file!
