Using AIX6.1 box.
I have UTC time value and need to convert it to local time value - I mean time zone and DST should be taken into consideration.
I hope it could be done using shell environment - I don't want to write a program.
thanks

ok I found it by myself - the difference between UTC and local time can be calculated:

Hi,
I need to convert a number representing time in UTC seconds to a date. Ex:
3BE0082C --> Oct 31 2001 15:31:08
I have tried the following perl command but it gives a different answer?
$ perl -e 'print scalar localtime(shift), "\n"' 3BE00B2C

Hi,
Is there any easy way to convert date time(stored in shell variable ) to epoch time in solaris box? As +%s is working on linux but not on solaris, also -d option is not working.
Any suggestion please? (6 Replies)

Okay, so let's say we have a string like:
20110105_193345
This represents:
January 5th, 2011 = 20110105
24-hour style time 19:33:45 = 193345
Okay, so we have our time. It's January 5th, 2011 at 19:33:45. I want to convert this time from Eastern Time Zone (which it currently is in)... (1 Reply)

Hi,

Hello AIX friends,
We have timezone settings on our AIX 6.1 boxes set to Europe/London.
How can I change it to UTC timezone with Daylight saving disabled.
After running "smit chtz_user" I don't see UTC option in the listing.
Please advise.

timedatectl
TIMEDATECTL(1) timedatectl TIMEDATECTL(1)NAME
timedatectl - Control the system time and date
SYNOPSIS
timedatectl [OPTIONS...] {COMMAND}
DESCRIPTION
timedatectl may be used to query and change the system clock and its settings.
OPTIONS
The following options are understood:
-h, --help
Prints a short help text and exits.
--version
Prints a short version string and exits.
--no-pager
Do not pipe output into a pager.
--no-ask-password
Do not query the user for authentication for privileged operations.
-P, --privileged
Acquire privileges via PolicyKit before executing the operation.
-H, --host
Execute the operation remotely. Specify a hostname, or username and hostname separated by "@", to connect to. This will use SSH to talk
to a remote system.
--adjust-system-clock
If set-local-rtc is invoked and this option is passed, the system clock is synchronized from the RTC again, taking the new setting into
account. Otherwise, the RTC is synchronized from the system clock.
The following commands are understood:
status
Show current settings of the system clock and RTC.
set-time [TIME]
Set the system clock to the specified time. This will also update the RTC time accordingly. The time may be specified in the format
"2012-10-30 18:17:16".
set-timezone [TIMEZONE]
Set the system time zone to the specified value. Available timezones can be listed with list-timezones. If the RTC is configured to be
in the local time, this will also update the RTC time. This call will alter the /etc/localtime symlink. See localtime(5) for more
information.
list-timezones
List available time zones, one per line. Entries from the list can be set as the system timezone with set-timezone.
set-local-rtc [BOOL]
Takes a boolean argument. If "0", the system is configured to maintain the RTC in universal time. If "1", it will maintain the RTC in
local time instead. Note that maintaining the RTC in the local timezone is not fully supported and will create various problems with
time zone changes and daylight saving adjustments. If at all possible, keep the RTC in UTC mode. Note that invoking this will also
synchronize the RTC from the system clock, unless --adjust-system-clock is passed (see above). This command will change the 3rd line of
/etc/adjtime, as documented in hwclock(8).
set-ntp [BOOL]
Takes a boolean argument. Controls whether NTP based network time synchronization is enabled (if available).
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
ENVIRONMENT
$SYSTEMD_PAGER
Pager to use when --no-pager is not given; overrides $PAGER. Setting this to an empty string or the value "cat" is equivalent to
passing --no-pager.
EXAMPLES
Show current settings:
$ timedatectl
Local time: Fri, 2012-11-02 09:26:46 CET
Universal time: Fri, 2012-11-02 08:26:46 UTC
RTC time: Fri, 2012-11-02 08:26:45
Timezone: Europe/Warsaw
UTC offset: +0100
NTP enabled: no
NTP synchronized: no
RTC in local TZ: no
DST active: no
Last DST change: CEST -> CET, DST became inactive
Sun, 2012-10-28 02:59:59 CEST
Sun, 2012-10-28 02:00:00 CET
Next DST change: CET -> CEST, DST will become active
the clock will jump one hour forward
Sun, 2013-03-31 01:59:59 CET
Sun, 2013-03-31 03:00:00 CEST
