01
Choose the code family first
The initial search is Asia/Shanghai in the time-zone group. Switching to country, locale, AWS or Kubernetes silently loads a suitable example and clears the previous selection.

An IANA time zone list is useful when a scheduler needs Asia/Shanghai rather than a guessed UTC+08:00. The named zone points to civil-time rules; a fixed offset does not carry future clock changes.
The same page separates country codes, locale codes, AWS Region codes and Kubernetes resource kinds. Select the family first: CN, zh-CN and cn-north-1 have different meanings even though their letters overlap.
Why use this IANA time zone list
A code is useful only when its family and source are clear.
Keep a zone name separate from an offset
The IANA time zone list uses geographic IDs from tzdb 2026d. It gives Asia/Shanghai and its country code, while deliberately avoiding a permanent UTC offset that could mislead a future schedule.
Tell similar-looking codes apart
A country code such as CN, locale tag zh-CN and AWS region cn-north-1 belong to different registries. The five data sets keep each code with its own fields, source and checked date.

02
Search names or exact identifiers
A city fragment, country name, two-letter code, Region name or resource kind can narrow its own group. Edit the search text and the old result becomes stale until Search or Enter runs again.
03
Check the source before copying
The selected card shows the source baseline and a link to the original registry or documentation. For AWS account access and Kubernetes cluster discovery, follow the source rather than treating this snapshot as a live probe.
Five code families in one scoped lookup
Geographic zones and country codes
The IANA time zone list contains 312 zone1970.tab locations; the companion iso3166.tab snapshot contains 249 country alpha-2 codes. Search a zone by ID, city or associated country name.
Common locale codes
Sixteen selected BCP 47 tags show language and region subtags. The plain en tag stays distinct from en-US; this list is a practical sample rather than every possible tag.
Cloud and cluster identifiers
Find 38 AWS Region codes across standard, GovCloud and China partitions, plus 16 Kubernetes resource kinds with apiVersion, plural name and scope.
What the snapshots can and cannot tell you
- Geographic zones are a subset
- This IANA time zone list follows zone1970.tab, not every accepted alias. A missing Etc/UTC or older name is not proof that software rejects it; consult the full tzdb.
- Offsets depend on dates
- The page stores zone identifiers, not current time or a permanent UTC offset. Clock rules change when governments revise them, and the browser's installed tzdata may differ from this snapshot.
- Code systems do not substitute for each other
- Country alpha-2 codes do not encode languages. Locale codes combine subtags, while AWS regions and Kubernetes kinds describe infrastructure; none can be inferred safely from a country alone.
- Availability belongs to the live service
- An AWS Region in this table may need opt-in or lack a given service. A Kubernetes kind here may be absent from your cluster, and custom resources are outside this 16-kind selection.
- Versioned reference, not a live feed
- IANA files are fixed at tzdb 2026d; locale, AWS and Kubernetes selections were checked on 2026-09-23. Opening this page sends no request to refresh registries.
IANA time zone list questions
How do I get the canonical IANA time zone IDs?
Start with the IANA time zone list's geographic IDs and open its zone1970.tab source. It omits backward-compatibility aliases, so use the full tzdb and your runtime when an older ID matters.
Is a time zone ID the same as a UTC offset?
No. Asia/Shanghai names a rule set; UTC+08:00 is only a numeric offset. A location can change rules over time, so store the named zone for future civil-time scheduling.
What is the difference between a country code and a locale code?
CN identifies a territory in the alpha-2 list. zh-CN combines a language subtag with a region subtag; it describes a locale rather than a country by itself.
Is an AWS Region code the same as an Availability Zone?
No. us-east-1 is a Region code; a zone designation is more specific and can be account-dependent. Check AWS account status and service availability separately.
How can I get apiVersion for a Kubernetes resource kind?
The selected built-in kinds show an apiVersion from the linked API reference, such as apps/v1 for Deployment. Run kubectl api-resources against your own cluster for its actual resources and versions.
