Background

A time zone represents an offset applied to Greenwich Mean Time (GMT) to obtain local time. The offset may vary throughout the year, if daylight savings time (DST) is used, or may be the same all year long. Typically, regions closer to the equator do not use DST. If DST is in use, then specific rules define the point at which the offset changes, and the amount by which it changes. Thus, a time zone is described by the following information:

If DST is observed, then three additional pieces of information are needed:

System and User Time Zones

ICU supports local time zones through the classes TimeZone and SimpleTimeZone in the C++ API. In the C API, time zones are designated by their ID strings.

Users may construct their own time zone objects by specifying the above information to the C++ API. However, it is more typical for users to use a pre-existing system time zone, since these represent all current international time zones in use. This document lists the system time zones, both in order of GMT offset, and in alphabetical order of ID.

Since this list changes one or more times a year, this document only represents a snapshot. For the current list of ICU system zones, use the method TimeZone::getAvailableIDs().

Notes

The zones are listed in binary sort order. That is, 'A' through 'Z' come before 'a' through 'z'. This is the same order in which the zones are stored internally, and the same order in which they are returned by TimeZone::getAvailableIDs(). The reason for this is that ICU locates zones using a binary search, and the binary search relies on this sort order.

You may notice that zones such as Etc/GMT+1 appear to have the wrong sign for their GMT offset. In fact, their sign is inverted because the the Etc zones follow the POSIX sign conventions. This is the way the original Olson data is set up, and ICU reproduces the Olson data faithfully, including this confusing aspect. See the Olson files for more details.

References

The ICU system time zones are derived from the Olson data at ftp://elsie.nci.nih.gov/pub. This is the data used by UNIX systems and is updated one or more times each year. Unlike the Olson zone data, ICU only contains data for current zone usage. There is no support for historical zone data in ICU at this time.

Time Zones in order of GMT offset

Zone listed in bold are the default zone for a given GMT offset. This default is used by ICU if it cannot identify the host OS time zone by name. In that case, it uses the default zone for the host zone offset.

Time Zones in order of ID

Zone listed in bold are the default zone for their GMT offset. This default is used by ICU if it cannot identify the host OS time zone by name. In that case, it uses the default zone for the host zone offset. See above for a description of columns. See note above for an explanation of the sort order.

Times suffixed with 's' are in standard time. Times suffixed with 'u' are in UTC time. Times without suffixes are in wall time (that is, either standard time or daylight savings time, depending on which is in effect).

Time Zone Equivalency Groups

ICU groups zones into equivalency groups. These are groups of zones that are identical in GMT offset and in rules, but that have different IDs. Knowledge of equivalency groups allows ICU to reduce the amount of data stored. More importantly, it allows ICU to apply data for one zone to other equivalent zones when appropriate (e.g., in formatting). Equivalency groups are formed at build time, not at runtime, so the runtime cost to lookup the equivalency group of a given zone is negligible.
