This does seem to be a bit vague. Here is a useful tip and in this case I am using the korn shell. The idea here is to temporarily define the TZ environment variable; that is....
would define the TZ var for the execution of the date command...regardless of what the default TZ setting is.
By example...
This isn't a ksh feature, it is standard behavior required for any shell conforming to the POSIX standards or the Single UNIX Specifications. But, the format shown above is not correct. A valid setting for TZ will include at least the zone's name and offset from UTC. The normal setting for Texas in the United States would be TZ=CST6CDT (not TZ=CDT) and TZ=UTC happens to work because the offset from UTC to UTC is 0, but the output from the commands:
will be identical except for the difference in the time zone name. Compare the results above with:
where you'll see a 6 hour difference in time (this time of year) as well as a difference in the time zone name. The output from the above three commands should be something like:

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

Any ideas? Thanks. :) (10 Replies)
Hello,
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
Vilius

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,
A few days ago I changed my CentOS box's timezone to -07:00.

rotatelogs
rotatelogs(8) System Manager's Manual rotatelogs(8)NAME
rotatelogs - rotate Apache logs without having to kill the server
SYNOPSIS
rotatelogs logfile rotationtime [offset]
DESCRIPTION
rotatelogs is a simple program for use in conjunction with Apache's piped logfile feature, which can be used like this:
CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
This creates the files /var/logs/logfile.nnnn where nnnn is the system time at which the log nominally starts (this time will always be a
multiple of the rotation time, so you can synchronize cron scripts with it). At the end of each rotation time (here after 24 hours) a new
log is started.
OPTIONS
logfile
The path plus basename of the logfile. If logfile includes any Otherwise, the suffix .nnnnnnnnnn is automatically added and is the
time in seconds. Both formats compute the start time from the beginning of the current period.
rotationtime
The rotation time in seconds.
offset The number of minutes offset from UTC. If omitted, zero is assumed and UTC is used. For example, to use local time in the zone UTC
-5 hours, specify a value of -300 for this argument.
PORTABILITY
The following logfile format string substitutions should be supported by all strftime(3) implementations, see the strftime(3) man page for
library-specific extensions.
%A full weekday name (localized)
%a 3-character weekday name (localized)
%B full month name (localized)
%b 3-character month name (localized)
%c date and time (localized)
%d 2-digit day of month
%H 2-digit hour (24 hour clock)
%I 2-digit hour (12 hour clock)
%j 3-digit day of year
%M 2-digit minute
%m 2-digit month
%p am/pm of 12 hour clock (localized)
%S 2-digit second
%U 2-digit week of year (Sunday first day of week)
%W 2-digit week of year (Monday first day of week)
%w 1-digit weekday (Sunday first day of week)
%X time (localized)
%x date (localized)
%Y 4-digit year
%y 2-digit year
%Z time zone name
%% literal `%'
