== Working with date & time magic words ==

Hi all, I am trying to find out how to use date & time [[WP:MAGIC|magic words]] and add/subtract a specific number of days or hours to them and then represent them in the format we use for signature. [I thought of using <nowiki>{{CURRENTTIMESTAMP}}</nowiki> and, adding, for example, 5000000 for 5 days, but that should not work properly at the end of a month.] Thanks! <span class="nowrap">&#8212;'''[[User:CX Zoom|CX Zoom]]'''[he/him]</span> <sup class="nowrap">([[User talk:CX Zoom|let's talk]] • {[[Special:Contributions/CX Zoom|C]]•[[User:CX Zoom/X|X]]})</sup> 12:36, 12 August 2022 (UTC)
:[[User:CX Zoom|CX Zoom]], you need to use [[UNIX time]]: {{#time:U}}. Five days from now: {{#time:c|@{{#expr:{{#time:U}}+432000}}}}<br style="margin-bottom:0.5em"/>As for the signature format, must be a system message that comes after [[MediaWiki:Signature]]. Can't remember what it is though. <span id="Alexis_Jazz:1660308392908:WikipediaBWLCLNVillage_pump_(technical)" class="BawlCmt">— <span style="color:#e08020">Alexis Jazz</span> ([[User talk:Alexis Jazz|talk]] or ping me) 12:46, 12 August 2022 (UTC)</span>
:See [[mw:Help:Extension:ParserFunctions##time]].  You may want something like <code>{<nowiki/>{#time:H:i, j F Y (e)|now + 5 days}}</code> which displays as {{#time:H:i, j F Y (e)|now + 5 days}}.  You'll need to check that the timezones displayed by e and asssumed by H etc are both the one you want. [[User:Certes|Certes]] ([[User talk:Certes|talk]]) 12:52, 12 August 2022 (UTC)

::[[User:Certes|Certes]], [[User:CX Zoom|CX Zoom]], that would only work for English Wikipedia and projects with the same timestamp format. There's [[:User:Alexis Jazz/Bawl/Mumbo jumbo/Timestamp support#Support table|a lot of variance across languages]] though. Well, I found the origin: https://gerrit.wikimedia.org/g/mediawiki/core/+/master/includes/parser/Parser.php#4636: <code><nowiki>$d = $this->contLang->timeanddate( $ts, false, false ) . " ($tzMsg)";</nowiki></code>. Not sure if the format can be retrieved on-wiki at all. <span id="Alexis_Jazz:1660323989327:WikipediaBWLCLNVillage_pump_(technical)" class="BawlCmt">— <span style="color:#e08020">Alexis Jazz</span> ([[User talk:Alexis Jazz|talk]] or ping me) 17:06, 12 August 2022 (UTC)</span>
