Usage: Merge DST in data rows using "|same dst=merge"

New page

{{Documentation subpage}}

This template creates 6 header cells in a table row: country code, coordinates, timezone name, comments, [[standard time|standard]] [[UTC offset]], and [[daylight saving time|DST]] UTC offset.

The two UTC offset header cells may be merged for list of timezones that do not use DST, using {{para|dst|no}}.

The headers are compatible with [[Help:Sortable tables|sortable tables]], and with 6-column {{tlc|Time zone/zone.tab cols...}} row templates:

* {{tl|Time zone/zone.tab cols wiki6}}
* {{tl|Time zone/zone.tab cols linked}}
* {{tl|Time zone/zone.tab cols unlinked}}

== Usage ==

{{tlc|Time zone/database header}} has one optional parameter {{para|dst|no}} to merge the two UTC offset header cells. By default, both header cells are shown:

{{demo|<nowiki>
{| class="wikitable sortable"
! {{Time zone/database header}}
|-
| {{Time zone/zone.tab cols wiki6|Asia/Hong_Kong}}
|-
| {{Time zone/zone.tab cols wiki6|America/Phoenix}}
|-
| {{Time zone/zone.tab cols wiki6|Europe/Berlin}}
|}</nowiki>}}

With {{tlc|Time zone/database header|dst{{=}}no}}, the two headers are merged. This may be useful if all following rows also have the DST cells merged, for example with {{tlx|Time zone/zone.tab cols wiki6|tz|same dst{{=}}merge}}:

{{demo|<nowiki>
{| class="wikitable sortable"
! {{Time zone/database header|dst=no}}
|-
| {{Time zone/zone.tab cols wiki6|Asia/Hong_Kong|same dst=merge}}
|-
| {{Time zone/zone.tab cols wiki6|America/Phoenix|same dst=merge}}
|}</nowiki>}}

If any timezone is updated and introduces DST, then the article editor will be responsible for manually removing the parameter. Otherwise, the UTC offset header will fail to describe the two columns:

{{demo|<nowiki>
{| class="wikitable sortable"
! {{Time zone/database header|dst=no}} !! Note
|-
| {{Time zone/zone.tab cols wiki6|Asia/Hong_Kong|same dst=merge}} || No DST
|-
| {{Time zone/zone.tab cols wiki6|America/Phoenix|same dst=merge}} || No DST
|-
| {{Time zone/zone.tab cols wiki6|Europe/Berlin|same dst=merge}} || Uses DST
|}</nowiki>}}
