When run on PowerShell(7) …
PS> $datePattern = '\d{4}-\d{2}-\d{2}'
'Today is 1999-12-31' -replace $datePattern, { [datetime]$PSItem.value }
... produces:-
'Today is 12/31/1999 00:00:00'
rather than (my Locale Pattern):-
'Today is 31/12/1999 00:00:00'
when:-
PS > Get-Culture -Debug
... produces:-
LCID Name DisplayName

Therefore, ‘12/31/1999 00:00:00’ should be ‘31/12/1999 00:00:00’.
