Re: 5250 and un-do

Hi Buck

In 7.3 it is possible to specify the number of fractional seconds, as IBM calls it, in a TIMESTAMP data type in RPG. It can go out to 12 decimal positions. Default is 6.

I'm not on 7.3 yet, so I haven't tested it. But this down to picoseconds.

There is apparently (google for timestamp and nanoseconds) an ISO 8601 standard that address this stuff. And apparently Java 8 can handle nanoseconds.

Db2 at 7.3 also supports these fractional seconds.

Regards
Vern

Excuse my ignorance but, What do you mean with timestamp " isn't enough any

TIMESTAMP records down to the microsecond (us - the 'u' is supposed to
emulate the Greek letter mu), and with a fast processor it is possible
to commit a pair of transactions in the same microsecond. If TIMESTAMP
resolved nanoseconds (ns) then that 'uniqueness' would be restored for
another few generations of processors :-)
