I (speaking for myself of course) would tend to agree that this would
represent an improvement and be worth the effort.

Points such as running the system clock on a UTC basis, having the system
automatically recognize local conventions such as daylight savings time,
having current time interfaces continue to return local time while new
interfaces provide UTC time, having the system clock value maintained using
established methods such as SNTP, etc. all seem like worthwhile objectives.

And having the ability to define whether or not a particular system
recognizes daylight savings time could take care of special cases such as
Indiana and/or situations where one didn't want an automatic time shift due
to daylight savings at say 2 in the morning (that is, wait until the system
activity is low/safe at 4:30 and then change the daylight savings time
attribute to yes).

Interesting thoughts for sure,
Bruce

If you're going this far why not allow the Operating System to call home
for
a correct time?  OS/2 did that long ago.

Hi, Vern:

Thanks for your message. That's fair at first glance. So we're saying we
can't improve the operating system because we have vendor Business Partners
who have special considerations, and it's our duty to protect them, thereby
ensuring that they don't have opportunity to remove those special
considerations? That's an interesting proposal indeed!

What if this was all *planned* and IBM were to state, "From VxRx forward,
the AS/400 will use GMT as its internal time of reference. All times
presented to the user will be *local,* having been adjusted according to
the user-specified UTC offset *TABLE* which is DST-aware." (This is not a
new concept... it's been on *nix systems, for example, for at least thirty
years.) Now, if IBM were also to allow (say via API) an application to
reference GMT (and the table in some fashion), the BP in question would be
(or at least should be) able to work off of that internal clock, thereby
eliminating such special operations once and for all. And what if (wonder
of wonders) the USER had the choice of specifying a fixed UTC-offset (ala
Indiana or China or ....), and would therefore be able to operate the tired
old way if s/he so chose?

As I read it, the thinking is "ApplicationX requires special steps in order
to accomodate DST. In order that we don't disrupt things and take away
ApplicationX's need for those special steps once or twice every year, we
can't touch the code." And we can't improve it for those who don't use
ApplicationX because ... umm ... because ... Am I missing something?

Now that I've stuck my foot out there to be smashed, I'll have a look at
the archives and see what the discussion included. But I'll tell you now
it'll be very hard to convince me that this sort of change isn't an
improvement that's well worth the effort.

I know that I'm way past "Everybody else has one, Mom. Why can't I?" but
come on, IBM.

Dennis
