Bruce,
Asked for elegant. Received elegant.
raku -e 'my $inst = now; put DateTime.new($inst).local, "\t",
DateTime.new($inst).truncated-to("second").local;'
2025-08-29T10:57:31.276115-04:00 2025-08-29T10:57:31-04:00
.truncated-to didn’t jump out at me when scanning class DateTime | Raku
Documentation<https://docs.raku.org/type/DateTime>, but I’ve got it now.
Thanks!
Mark

In the end, I’m looking for elegant mechanics to get DateTime objects from
multiple sources (including now), perform calculations, etc., then produce this
format using .Str:
YYYY-MM-DDTHH:MM:SS-04:00
not this format:
YYYY-MM-DDTHH:MM:SS.806520-04:00
Hi Mark,
This should work:
raku -e 'say DateTime.now.truncated-to("second");'
