What is an Epoch Unix Timestamp?
The Unix Epoch (also referenced as POSIX time) is a standardized counting routine designed by computer scientists to measure time as a single running integer. It represents the cumulative count of **seconds that have elapsed since midnight on January 1, 1970 Coordinated Universal Time (UTC)**, excluding leap seconds.
Why Do Software Developers Use Epoch Timestamps?
Epoch timestamps are highly favored across coding systems (databases, APIs, logging infrastructures) because integers are extremely light to index, transfer, and query compared to standard alphabetical calendar strings. They avoid common errors associated with global time-zones, formatting differences, or daylight savings offsets during logical comparisons.
Decoding Seconds vs Milliseconds
Epoch timestamps generally exist in two common formats:
- Seconds (10 digits): Standard POSIX timestamp measuring elapsed seconds (e.g. 1779450000). Highly incorporated in standard database indexes.
- Milliseconds (13 digits): Detailed clock measurements utilized by programming frameworks like JavaScript (e.g. 1779450000000).
