'datetest' fails when given default 'date' strings as date arguments

[BMJ-pdx]

'datetest' cannot make sense of default 'date' output:

$ datetest "$(date)" --eq "$(date)"
dtest: cannot make sense of `Mon May 19 15:58:14 PDT 2025' using the given input formats

Hi,
yes, this is correct. You need to use date -I or date -Iseconds. The default date output is both locale dependent and in local time.
