In SEQUEL, it's CVTDATE(yourdate,ymd1). Plus, it'll be invaluable in
finding
bogus dates your application software package stuffed into your files. 

I just found a case where an A/R aging routine made a bunch of due dates
equal to 20070931 for customers whose terms code is thirty days, and the
invoices were created on September 1st. This was following a package
upgrade
done in August. Don't software companies have people to test their code
anymore? Sheesh.

Depends what you mean by easy!!

Something like a bunch of character casts and substrings is what you do.

date(substr(char(yourdate), 1, 4) concat '-' concat
substr(char(yourdate),
5, 2) concat '-' concat substr(char(yourdate), 7, 2))

will get you the date in a date data type - similarly, do that with
yourtime

time(substr(char(yourtime), 1, 2) concat ':' concat
substr(char(yourtime),
3, 2) concat ':00')

Better yet, write a user-defined function that'll take the integer and
return the date - much cleaner - and RPG can do the conversion much more
neatly.
