|Description:||Recording of a point in time|
A Timestamp is a recording of a point in time, typically used as meta data for events or documents. .
It can be textual or an integer, human readable or encoded into binary and requires the definition of a reference system.
For textual Timestamps it is important to specifiy the Timezone:
1662618414- Unix Timestamp
This is the moment when writing this in seconds since the Unix Epoch.
Timestamps for Network-Protocols are explained in , generic Timestamps in ISO 8601.
Unlike a PC none of the Box-Models has a battery buffered hardware RTC, that is why hwclock or timedatectl are not installed.
The Unix time is zero at boot time and starts with the Unix Epoch.
Once a connection to the Internet is established the system time is corrected using NTP or SNTP.
There are further methods to get a valid system time offline, see the RTC article.
The minimum Timestamp recorded is the
last modified time, but some filesystems also store
creation time and
last access time for each stored object.
