I wanted to do some date manipulation in rc awhile back and ended up
writing some utils to manipulate ISO8601 dates.
% 8601/date #current date in YYYY-MM-DDTHH:MM:SS+TZ:TZ
% 8601/delta `{8601/date} + P1DT #gives tomorrows date (the P1DT is
an 8601 "period" format, in this case 1 Day. could equivalently use
PT24H or PT86400S. or PT12H43200S if you were so inclined...)
Never got around to licensing it but feel free to use it,
