Search for a value of X hours ago

[P C]

Hello,
I would like to seek in the database a value of 6 hours ago.

I guess it's the next tag that he will use,

$current($timestamp=some_time, $max_delta=delta_t,$data_binding=binding_name).obstype[.optional_unit_conversion][.optional_rounding][.optional_formatting]

But it lacks examples so that I can understand it. (I'm not bilingual and sometimes I have difficulty for some things)

Thank you in advance !

<p>The temperature 6 hours ago was: $current(timestamp=$current.dateTime.raw - 1800).outTemp</p>

Merci Tom, c'est plus clair avec un exemple !

Oui, théoriquement 21600 secondes

« delta_t is the largest time difference (in seconds) between the time specified and a timestamp of a record in the database that will be returned. By default, it is zero, which means there must be an exact match with a specified time for a record to be retrieved.»
