Important: #103496 - ISO format used for date rendering¶
See forge#103496
Description¶
The default format for date rendering configured in $GLOBALS['TYPO3_CONF_VARS']['SYS']['ddmmyy']
has changed.
The former arbitrary 'd-m-y'
format was replaced with the standard ISO 8601 'Y-m-d'
format.
Examples of dates where the 'd-m-y'
format led to unclear dates:
- A 2-digit year could also be a day in a month:
21-04-23
could be understood as2021-04-23
instead of2023-04-21
. - The century of years could not be distinguished:
21-04-71
could be2071-04-21
or1971-04-21
This affects date display in various locations so code relying on the previous format (e.g. acceptance tests) must be updated accordingly.
