Timezone II

The Timezone II cookbook contains recipes for installing the latest tzdata (a.k.a. IANA or Olson) timezone database and setting the timezone on your system. It is a fork of the timezone cookbook by James Harton.

Requirements

This cookbook is known to work with:

• Amazon Linux
• CentOS and RHEL
• Debian
• Fedora
• Gentoo
• PLD Linux
• Ubuntu

It should work with any OS that uses the IANA/Olson timezone database and stores local timezone data in /etc/localtime (the only OS I know of that does not do this is MS Windows). However, some OSs not mentioned above have their own system utility for setting the timezone, and this may overwrite the changes made by this cookbook.

Attributes

Key	Type	Description	Default
['tz']	String	the timezone name as defined in tzdata	UTC
['timezone']['tzdata_dir']	String	the path to the root of the tzdata files; the default value is for most known distributions of Linux	/usr/share/zoneinfo
['timezone']['localtime_path']	String	the path to the file used by the kernel to read the local timezone's settings; the default works for Linux and other *ix variants	/etc/localtime
['timezone']['use_symlink']	Boolean	whether to use a symlink into the tzdata tree rather than make a copy of the appropriate timezone data file (linux-generic recipe only)	false

Usage

Set the "tz" attribute to your desired timezone and include the "timezone-ii" recipe in your node's run list:

{
  "name": "my_node",
  "tz": "Africa/Timbuktu",
  "run_list": [
    "recipe[timezone-ii]"
  ]
}

timezone-ii::default

The default recipe will first install or upgrade the IANA/Olson timezone database package for your OS (timezone-data on Gentoo, tzdata on all others). Then it will call one of the recipes below according to your node's platform.

timezone-ii::debian

This changes the timezone on Debian and Debian-derived systems by:

1. writing the value of tz to /etc/timezone, then
2. calling dpkg-reconfigure tzdata.

Only the tz attribute is used; all others are ignored.

timezone-ii::fedora

This changes the timezone on Fedora by calling timedatectl set-timezone with the value of tz.

Only the tz attribute is used; all others are ignored.

timezone-ii::linux-generic

This changes the time on all OSs without a more specific recipe. It assumes that the kernel gets data on the local timezone from /etc/localtime. (This is true for FreeBSD as well as Linux, so "linux-generic" is a bit of a misnomer.)

What this recipe does:

1. verifies that the value of tz corresponds with a timezone data file under the directory specified in timezone.tzdata_dir (default: /usr/share/zoneinfo), then
2. creates a copy of or symbolic link to that data file in the path specified in timezone.localtime_path (default: /etc/localtime).

The truthiness of timezone.use_symlink (default: false) determines whether a symlink or a copy is made.

timezone-ii::pld

This changes the timezone on PLD Linux. It writes the appropriate timezone configuration file, making use of the tz and timezone.tz_datadir attributes. Other attributes are ignored.

timezone-ii::rhel

This changes the timezone on RedHat Enterprise Linux (RHEL) and CentOS. It updates the /etc/sysconfig/clock file with the value of the tz attribute, then calls tzdata-update to change the timezone. All node attributes other than tz are ignored.
