date format getting changed from yyyy-mm-dd hh:mm:ss:fff to dd-mm-yyyy hh:mm

That's unexpected and not in line with my screenshot from above, which does not feature the extra "HH".

What happens if you run the following line after the original three you've repeated above?

$host.CurrentCulture.DateTimeFormat | Format-List -Property *pattern;

You should see an enumeration of the various formats as shown below, with the change in format reflected in the FullDateTimePattern property:
