Date and Time
|
||
~~~~~~~~~~~~~
|
||
|
||
We format date and time in accordance with ISO 8601, that is: YYYY-MM-DD and
|
||
HH:MM:SS (24-hour clock).
|
||
|
||
For more information, see: https://xkcd.com/1179/
|
||
|
||
Unless otherwise noted, we display local date and time.
|
||
Internally, we store and process date and time as UTC.
|
||
|
||
|
||
.. rubric:: TIMESPAN / INTERVAL
|
||
|
||
Some options accept a TIMESPAN or an INTERVAL parameter, which can be given as
|
||
a number of years (e.g. ``2y``), months (e.g. ``12m``), weeks (e.g. ``2w``),
|
||
days (e.g. ``7d``), hours (e.g. ``8H``), minutes (e.g. ``30M``), or seconds
|
||
(e.g. ``150S``).
|
||
|
||
The ``borg prune`` ``--keep-*`` retention options accept either a plain count
|
||
(e.g. ``--keep-daily 7``, keeping up to 7 daily archives) or a time interval
|
||
(e.g. ``--keep-daily 7d``, keeping one daily archive per day within a 7-day window).
|
||
When using interval-based retention, ``--from`` may be specified to set the
|
||
reference timestamp for the interval (defaults to the current time).
|
||
|
||
Please note that Borg treats months (e.g. ``12m``) as fixed 31-day periods
|
||
rather than calendar months. As a result, ``12m`` corresponds to
|
||
12 × 31 = 372 days. Similarly, years (e.g. ``2y``) are treated as fixed
|
||
365-day periods and do not take leap years into account.
