A Unix timestamp (or epoch time) counts the seconds or milliseconds that have elapsed since 00:00:00 UTC on January 1, 1970. It provides a universal time standard for computer systems worldwide. This time representation is independent of time zones and daylight saving time, making cross-platform and cross-regional time synchronization, event logging, and interval calculations straightforward. It is a core time format widely used in development, logging, and data storage.
Unix timestamps are commonly expressed in two forms: seconds (10 digits) and milliseconds (13 digits), such as 1678901234 (seconds) and 1678901234567 (milliseconds). Their numeric nature facilitates programmatic calculation, sorting, and storage, avoiding inconsistencies in date formats. They are particularly crucial in databases, API interfaces, system logs, and distributed applications, forming the technical foundation for ensuring time consistency and processing efficiency.
This tool supports two-way conversion between seconds and milliseconds timestamps, can convert Unix timestamps to local time or UTC in real time, and can quickly convert standard date-time values to corresponding timestamps. It also provides features like dynamic display of the current timestamp, generating timestamps from custom dates, and one-click copying of results. Suitable for time-handling needs in various development contexts such as JavaScript, Python, PHP, and Java.
As system architectures evolve, modern applications commonly use 64-bit timestamps to address the Year 2038 problem. Unix timestamps play a key role in web development, mobile apps, IoT, data analysis, and other fields. Their standardization, cross-platform compatibility, and computational efficiency make them an indispensable time representation scheme in the digital era. This tool aims to provide developers and general users with a simple, accurate, and instant online timestamp conversion service.
Quickly convert between timestamps and standard time, supports seconds and milliseconds formats, suitable for development and daily use.
