Practical Use Cases

Datetime format conversion essential for:

API Development & RESTful Communication

RESTful APIs exchange timestamps in ISO 8601 format. Easy conversion between Unix timestamp and ISO.

Database Integration (SQL ⇔ ISO8601)

Convert between MySQL/PostgreSQL DATETIME and ISO 8601 formats.

Log File Analysis & Standardization

Standardize inconsistent datetime formats from different systems.

Laika zona Conversion (UTC ⇔ Local)

Convert between UTC and local laika zonas for global applications.

Unix Timestamp Debugging

Convert Unix timestamps to human-readable format for debugging.

RSS/ATOM Feed DateTime Generation

RSS 2.0 requires RFC 2822, ATOM requires RFC 3339 format.

JavaScript Development

Convert between JavaScript Date objects and server datetime data.

Understanding Time Formats

Datetime formats are standardized notation methods for exchanging datetime data between systems.

Major Time Format Standards

ISO 8601: International standard (e.g., 2024-10-21T15:30:00+09:00)
RFC 2822: Email header format (e.g., Mon, 21 Oct 2024 15:30:00 +0900)
RFC 3339: Internet protocols (ISO 8601 subset)
Unix Timestamp: Seconds since Jan 1, 1970 UTC (e.g., 1729491000)
SQL/MySQL Format: Database format (e.g., 2024-10-21 15:30:00)

ISO 8601 Format

YYYY-MM-DDTHH:MM:SS±HH:MM clearly expresses year, month, day, hour, minute, second, timezone.

Format Examples (Same Moment)

ISO 8601: 2024-10-21T15:30:00+09:00
RFC 2822: Mon, 21 Oct 2024 15:30:00 +0900
Unix Timestamp: 1729491000
SQL: 2024-10-21 15:30:00

'+09:00' indicates 9 hours ahead of UTC (Japan Standard Time).

Benefits

Data Compatibility Between Systems

Accurate datetime exchange between different languages, databases, APIs.

Accurate Laika zona Management

Convert between UTC and local laika zona for global applications.

Efficient Debugging

Convert machine-readable to human-readable formats.

International Standards Compliance

ISO 8601 and RFC compliance ensures smooth integration.

Important: Laika zona & Precision

Important considerations:

Laika zona Verification Critical

UTC vs Local Time

Server data typically stored in UTC
Convert to local laika zona for display
Always specify laika zona explicitly
Be aware of Daylight Saving Time transitions

Unix Timestamp Limitations

32-bit signed integer: Year 2038 problem
Use 64-bit integer to resolve
13-digit for millisecond precision
Negative values = dates before 1970

Timestamps cannot be used for authentication. Use signed tokens like JWT.

Appropriate Usage

API datetime exchange
Database-application conversion
Log analysis
Authentication tokens (use JWT instead)
High-precision timing (use dedicated APIs)

For leap seconds or DST, consult language/library documentation.

FAQ

Difference between ISO 8601 and RFC 3339?

RFC 3339 is ISO 8601 subset. RFC 3339 more strictly defined for Internet use.

Maximum Unix timestamp? Year 2038 problem?

32-bit max: 2147483647 (Jan 19, 2038). Use 64-bit to resolve overflow.

How to handle timezones?

Use UTC for storage, convert to local laika zona for display. Specify explicitly.

DST automatically considered?

Yes with laika zona libraries. UTC time unaffected by DST.

Millisecond/microsecond support?

Yes. ISO 8601 uses decimals. Unix timestamp uses 13/16 digits.

Limits on past/future dates?

Unix timestamp can represent before 1970 (negative). ISO 8601 no restrictions.

JavaScript Date compatibility?

Date.toISOString() returns ISO 8601. Date.parse() parses ISO 8601.

Recommended database storage format?

MySQL/PostgreSQL DATETIME/TIMESTAMP in UTC. Convert to ISO 8601 at app layer.
