Looks good! I haven't checked the specs of the RFC-822 completely,
but, yes if any of the number is has a single digit, it should be
prepended by a "0" (zero).
One minor correction needed, though. The date/day should also go
through the form-num function. So maybe the form-num function could be
made global.
I have reproduced Gregg's script along with the minor changes:
form-num: func [num] [either 1 = length? num: form num [join #"0" num] [num]]
to-itime: func [
"Returns a standard internet time string (two digits for each segment)"
time [time!]
][
rejoin [form-num time/hour ":" form-num time/minute ":" form-num
time/second]
]
to-idate: func [
"Returns a standard Internet date string."
date [date!]
/local str
][
str: form date/zone
remove find str ":"
if (first str) <> #"-" [insert str #"+"]
if (length? str) <= 4 [insert next str #"0"]
head insert str reform [
pick ["Mon," "Tue," "Wed," "Thu," "Fri," "Sat," "Sun,"] date/weekday
form-num date/day
pick ["Jan" "Feb" "Mar" "Apr" "May" "Jun" "Jul" "Aug" "Sep"
Oct
"Nov" "Dec"] date/month
date/year to-itime date/time ""
]
]
