Daylight savings is part of the "timezone" setting, which in turn is part of the environment for every process. You can (in principle) set different timezone settings for each process you start by modifying the "TZ" variable.

This means that no reboot is necessary at all. If you have an application the system runs this application usually runs under a certain user-ID for this purpose. Set the "TZ" variable either in this users environment and then restart the application to make sure all processes are started with the new setting or change the machine-wide setting itself (you can use SMIT for this).

You may want to reboot your system anyway to make sure every running process has definitely this new setting in its environment but this is not required at all, it would be more of a "make 110% sure"-measure.

I hope this helps.

NAME
coreadm - application core file administration SYNOPSIS
DESCRIPTION
system call is used to specify the location and pattern for core files produced by abnormally terminating processes. See core(4). This system call can be used to specify a system wide location for core file placement and/or a process specific pattern. The structure, is used to specify a system wide or a per-process core file pattern and also specify the current system wide core file set- tings. is defined in the header Member Type Member Name Description char c_pattern The core file pattern. uint64_t c_flags Core file settings. Parameters is expected to be set to It is critical for future backward compatibility that the macro itself be used and not its value. is the core file pattern. A core file name pattern is a normal file system path name with embedded variables, specified with a leading character, that are expanded from values in effect when a core file is generated by the operating system. An expanded pattern length greater than will be truncated to The possible values are: c_flags is used to control the system wide core file settings. The flag values can be combination of Enable/Disable creation of global core files. Enable/Disable creation of per-process core files. Enable/Disable creation of global core files for processes. Enable/Disable creation of per-process core file for processes. If a flag value is not set, then the option is disabled. For per-process core file setting, c_flags can either be 0 or The former disables core file creation (for that process) and the latter enables it. c_pid Should be a (valid) pid of a target process or 0. If c_pid is zero, then the settings are applied to global core file settings. If c_pid is 1, then the settings are applied to init(1M). c_in If non-NULL, then the values will be used as new core file settings. If this is NULL, then the c_out parameter is expected to be non-NULL and system call is used to interrogate the current settings. c_out If non-NULL, the current settings are returned in this parameter. RETURN VALUE
Upon successful completion, returns 0. Otherwise, a value of -1 is returned and is set to indicate the error. ERRORS
fails and does not change the core file settings if the effective user-ID of the calling process is not a user having appropriate privileges. The input or output parameter passed to is an invalid address. The core file pattern or flags is invalid. The specified PID is non-zero and does not exist. EXAMPLES
1. Enable global core file creation using the pattern (core.process-ID.machine-name) in the location 2. Enable per-process core file pattern for the process-ID passed in as argument. The core file will be placed in The pattern is (core.process-ID.time-stamp). 3. Enable a per-process pattern of core.CUP-ID for all processes in the system (init(1M) core file setting). NOTE: This has to be run during system startup or reboot the machine after setting this for the settings to take full effect. SEE ALSO
