Re: Daylight Savings Time and NTP

The question becomes "why do you care"?  Replace the term "hardware clock" 
with "system clock"  and look at the V5R3 Memo to Users.
>From that document:  "The software clock is a system facility that can be 
set to a different time than the system clock and uses the QUTCOFFSET 
system value to calculate the UTC time. Since the software clock is not 
integrated with the rest of the system, it will be removed in a future 
release."  I bet it won't be long until system QUTCOFFSET dies also.

You can actually be using the same API's, just recompile the programs 
using those api's and they will  change from one clock to another.  All of 
this is in the memo to users also.

See also new system value:  QTIMZON.  Granted, I'm from Indiana and 
couldn't give a rip about time change.

System value . . . . . :   QTIMZON 
Description  . . . . . :   Time zone 
 
 
Time zone  . . . . . . :   QN0500EST2     Name
 
 
Associated settings: 
  Offset . . . . . :   -05:00 
  Full name  . . . :   Eastern Standard Time 
  Abbreviated name :   EST 

What you don't find in the Memo to Users may be covered in the Software 
installation.  There are some data area's you create, etc, on your V5R2 
machine to prepare for this new system value, etc in V5R3.

It's just all automatic now.  Upgrade before this weekend.  :-)

Re: Daylight Savings Time and NTP






Does V5R3 support changing the hardware clock as well as the software 
clock?  I bought a software package for about a hundred bucks that does 
both.  Just wondering if I still need it.
