Whenever a database variables (such as a boolean for example) gets updated, you can the timestamp when the update was done:
{% input custom.filing.check as:boolean assign:check_filing %}
{{ check_filing.updated_at | date:"%d/%m/%Y %H:%M" }}
However, this gives you a timestamp in CEST, so whenever you did the update in another timezone, that information would not be what you expect it to be.
But we have a specific date-filter for this, called localized_date
, which gives you the correct timestamp depending on your local settings:
{{ check_filing.updated_at | localized_date:“%d/%m/%Y %H:%M” }}
