Epoch time (also called Unix timestamp) is the number of seconds or milliseconds that have elapsed since January 1, 1970 (UTC), excluding leap seconds. It is widely used in programming and databases for storing time values as integers.
ISO 8601 format represents dates and times as YYYY-MM-DDTHH:mm:ss.sssZ. For example, 2025-07-12T14:30:00Z represents July 12, 2025 at 2:30 PM UTC. Our tool supports all ISO 8601 variants.
The correct format of time stamping depends on your use case: Unix timestamp (integer) for storage and comparison, ISO 8601 string for API communication, RFC 2822 for email headers, and SQL datetime for database queries. Our converter supports all these formats.
TimeFormatConversion.com supports over 100 date-time formats including Unix timestamps, ISO 8601, RFC 3339, RFC 2822, SQL datetime, military time, decimal time, Julian dates, and more.
