In which format does Zabbix store timestamps for all values?

Zabbix stores timestamps in UNIXTIME format, which represents time as a single integer value denoting the number of seconds that have elapsed since the Unix epoch (00:00:00 UTC on January 1, 1970, excluding leap seconds). This format is widely used in computing for its simplicity and efficiency in calculations involving time.

Using UNIXTIME allows for easy interoperability between various systems and programming languages, as it is a standard format understood across platforms. This makes it particularly beneficial for logs, timestamps, and data storage, ensuring that the Zabbix system can efficiently manage and query time-related data without ambiguity.

While formats like ISO 8601 provide human-readable timestamps, they are not as efficient for storage and processing as UNIXTIME. UTC time is a time standard that can be represented in various formats, and local time refers to time adjusted for time zones, which may vary between users and systems. However, the underlying storage in Zabbix relies on the straightforward and computation-friendly UNIXTIME format for all values.
