Show TYPO3 content only during working hours by recurrently publish and unpublish content every working day - typo3

Question

I want to display a TYPO3 content element every Monday till Friday between 9am and 5pm. With the default options I am only able to add a single publish and a single expire date and time.
How could I mange this in TYPO3 v10 (on the server side without using JavaScript)?
I found an extension (Content Scheduler), that can manage recurring publishing and unpublishing dates but it's not possible to define s.th. like 'every working day'.
I was thinking about using the TYPO3 scheduler (or native cron job) calling a CLI command but TYPO3 does not offer a command to publish and unpublish content elements.
Any ideas? Maybe using the good old TypoScript?

Answer 1

All visibility timings of records is not periodical but on fixed dates (and times) for starting and/or ending of visibility.
The only option I know where you can ignore parts of the full timestamp are conditions in TypoScript.
The condition for TYPO3 10 is described in this manual
this will result in a typoscript like this:
[date("G") > 8 && date("G") < 17]
page.10.variables.content < styles.content.get
[else]
page.10.variables.content = TEXT
page.10.variables.content.value = Sorry. we are closed.<br />Please come back at 9:00.
[global]
Of course this will not consider the weekend and you need to enhance it.
Note that you can't stack conditions into each other!
[date('N') > 5]
// just saturday and sunday:
page.10.variables.content = TEXT
page.10.variables.content.value = Sorry. we are closed.<br />Please come back on Monday at 9:00
[date('N') == 5 && date('G') > 16]
// friday in the evening
page.10.variables.content = TEXT
page.10.variables.content.value = Sorry. we are closed.<br />Please come back on Monday at 9:00
[date("G") > 8 && date("G") < 17]
page.10.variables.content < styles.content.get
[else]
page.10.variables.content = TEXT
page.10.variables.content.value = Sorry. we are closed.<br />Please come back at 9:00
[global]
You also can compute these conditions in FLUID. Either with apropiate variables you provide (for dayOfWeek and hour)
or with a matching viewhelper:
If you want to use PHP to provide different content at different times in the week you can do it with:
your own userFunction for your own condition
or your own ViewHelper
or an controller for special content which handles it internally
