Re: Single Partition Supporting multiple time zones

Hi, Paul and Vern and Mohammad:

As far as I know, the IBM i OS does not really do much with that "locale" information. Your applications would need to retrieve the currentuser's locale and use that information to do something appropriate, for example, as Larry Bolhuis suggested, you could set the system date to UTC and store all date-time stamps in any database tables or files as UTC, and then whenever you display date/time on a screen or report, use the locale to adjust what the user sees to "local time". Not a trivial effort, as it requires changes to the applications.

I think this is why IBM only went "so far" when they added "timezone support" to the OS, back in V5R3... too many issues that could have adverse impacts on user applications.

Looking at the source for EN_US locale, at the very bottom are the time entries.
In theory, you could control the time by setting each user profile to a locale for their time zone.
Locale . . .

I'm not sure of the impact of system jobs, would not be able to have multiple times for those jobs.
