Some countries are divided into more than one time zone.
The most interesting multizone countries are listed on this page.
The data were compiled from many sources, not always authoritative.
Information about the zone times and DST rules are extracted from the TZ database. More information on the 'tz database' can be found on the IANA TZ web page.
DST: daylight saving time, summer time.
UTC: universal time, the time on the 0° meridian without DST.
Please note that time zone borders, observing DST, DST on/off times and dates sometimes change.
Hence: this page is only a snapshot in time.
USA observes new DST rules per 2007, according to:
Public Law 109-58, Energy Policy Act of 2005, Sec. 110. Daylight savings.
DST on (+1 hour): second Sunday of March, 02:00 local time.
DST off: first Sunday of November, 02:00 local time.
Indiana observes DST starting 2006 (April 02).
The official decision is published by DOT:
Department Of Transportation (DOT), Office of the Secretary
49 CFR Part 71 ET, OST Docket No. 2005-22114
Several counties in Indiana changed their minds and departed from the Indiana rule.
Official information on the Indiana changes can be found at govpulse.
The time zones and the daylight saving time are defined in the The Uniform Time Act of 1966 (15 U.S.C. 260a(a)).
The time zone boundaries are very precisely defined in the US Code of Federal Regulations, Title 49 (Transportation), Subtitle A (Office of the Secretary of Transportation), Part 71 (Standard Time Zone Boundaries).
The Department of Transportation is in charge of the time zones, as stated in the Uniform Time Act.
The text of Title 49 is available through the U.S. Government Printing Office. Search for 49CFR71 on the Electronic Code of Federal Regulations website.
The table below is believed to be in accordance with the March 2013 version of the Standard time zone boundaries regulation CFR Title 49, Part 71.
Not mentioned are the exemptions, made for rail carriers in the central zone. They are allowed to use other timezone changing points between central and mountain time.
Some reported exceptions to the federal rules were added in the table below. Some of the exceptions were noted by Steve Jones, OnTimeZone.com.

The number of actual time zones is not clear.
The US Embassy in Ulaanbaatar claims that there is only one UTC+8 time zone.
Many sources (e.g. the Embassy of Mongolia, Washington, USA) claim that Mongolia has two time zones UTC+7 (west) and UTC+8.
Some sources, e.g. the TZ distribution, claim that Mongolia has three time zones with UTC+7, UTC+8, UTC+9. The TZ distribution has Dzavhan and Govi-Altay in the UTC+7 zone.
Information (2005-03-25), from a reader of the Mongolian UB Post, says that Mongolia has 4 time zones since 2005. The Sukhbaatar (Sühbaatar) aymag is on UTC+8.5
It is difficult to obtain reliable information about time zones in Mongolia, so use the listed information with care.

The following table lists all zones as a function of the longitude.
| Longitude (°) | zone time | Longitude (°) | zone time | |
|---|---|---|---|---|
| 7.5E - 7.5W | 0 | 7.5W - 7.5E | 0 | |
| 7.5W - 22.5W | -1 | 7.5E - 22.5E | 1 | |
| 22.5W - 37.5W | -2 | 22.5E - 37.5E | 2 | |
| 37.5W - 52.5W | -3 | 37.5E - 52.5E | 3 | |

| 172.5W - 180W | -12 | 172.5E - 180E | 12 |
This can be expressed as an algorithm:
Longitude: east is positive, west is negative.
if (longitude >= 0): zone time = integerPart((longitude + 7.5)/15)
if (longitude < 0): zone time = -integerPart((-longitude + 7.5)/15)
