[PHP] timezone

I found some code at php.net that does this:

$deftz = date('T');

You need to set the default time zone in this fashion,

But I don't know the timezone - I'm trying to get it so I can convert
times I get from the database to a user requested timezone.

But do you ACTUALLY know what time zone is stored IN the database? What if te
database was from another server?
One of the 'standards' adopted when working world wide is to ensure what is
stored IN the database is always UTC based. So you can always compare times on
the same consistent base. The only time you need the offset is to display a
local time, and that is either the time local to the server, or the time local
to the client.
The 'default' timezone is not necessarily the right one in either case ;)

I misspoke - the data in the db is in UTC. This is used to covert the
time of day on the server to the user's local timezone.

You are aware that the code you used is really bad practice, right?
You're basically hiding the error no default timezone set by getting
the default timezone, which returns an error; surpressing that error,
providing the date_default_timezone_set function with the default value
of date_default_timezone_get if none is defined (which there should!!),
being UTC.
So in short, you're saying set the default timezone to the default
timezone if no timezone is set, which I know there is not. That's very
hard to understand for future programmers reading your code. Why not
just set date_default_timezone_set('UTC'). It's clear, resolves the
warning and works perfectly, instead of relying on vague defaults
somewhere, in the hope they're set right.
On a sidenote; the reason why your original fix did not work:
$deftz = date.timezone;
Is because date.timezone is an ini setting. Not valid PHP code. And the
error actually tells you you need to SET date.timezone, not set a
variable TO the ini setting. In other words, you wanted date.timezone =
UTC instead of $tz = date.timezone (which makes no sense anyway)

But UCT is not the timezone. When this app runs in New Mexico (where I
am) it's Mountain time. When it runs in NY it's Eastern. When it runs
in Tokyo it's JST, etc. The user has the option of setting the
timezone all times are displayed in. They can select any timezone
regardless of where they are. The app displays the last update time in
the user selected TZ. So I have to convert the time I get from the
server to that.

Most servers provide UTC time regardless of the exact timezone they are situated in and then leave it to the user to show it in the right timezone to the user. The timezone you want to set is the timezone you GET the time in. Not necesserily the timezone your device resides in.

You don't need to convert anything! Store as unix timestamps, and call

[PHP] timezone math problem.
I have the following: #!/usr/local/bin/php ?php $offset = date(Z); $sDate = '2010-09-16'; $sTime = '00:00:00'; $eDate = '2010-09-17'; $eTime = '00:00:00'; $tmpStart0 = date($sDate $sTime); $tmpEnd0 = date($eDate $eTime); $startDate = date(Y-m-d H:i:s,strtotime($tmpStart0 . - . $offset seconds)); $endDate = date(Y-m-d H:i:s,strtotime($tmpEnd0 . - . $offset seconds)); $when = timestamp BETWEEN \$startDate\ AND \$endDate\; echo \n$offset\n$when\n\n; ? Which returns: machine1 (AST) PHP 5.2.6: -10800 timestamp BETWEEN 2010-09-16 03:00:00 AND 2010-09-17 03:00:00 machine2 (MST) PHP 5.1.6: -21600 timestamp BETWEEN 1969-12-31 17:00:00 AND 1969-12-31 17:00:00 Aside from upgrading the second box, is there some other logic that is wrong?

You are correct, sir!
This is why you may want to check into using date(O); to check the offset.

Re: [PHP] Timezone offset
Since about the US and most of the world that still do daylight savings started doing so, which was bout WWII. Most of Europe does, we changed this past weekend. We don't match the US in the dates, but we do it. In the Southern Hemisphere they do it the opposite way, since summer and winter come in opposite months of the calendar, so time differences with countries in different hemispheres (north south) might move about 2 hours along the year.

You can use date( 'I' ) to determine whether or not your server is

This project will be on a Windows server for a lot of the functions I have found on PHP.net don't work right. I am storing all the dates on the database in GMT time, thus I take the users input dates and convert them to GMT based on their timezone. Plus convert from GMT to their timezone. I would also like a function that can tell me to offset with DST. Example; I give it EST it would right now return -4, not -5 because of DST. I have looked a the PEAR Date_TimeZone class, it looks good, but there is no doc or examples on how to use it. Can someone recommend some good functions to using, that work on a windows platform.

RE: [PHP] timezone problem
Hi Baba I've been trying to get as much info on this as possible and you are right it is quite messy. Thanks for that link, I'm going to take a look at your code. -Original Message- From: Baba Buehler [mailto:[EMAIL PROTECTED]] Sent: May 21, 2002 5:37 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] timezone problem Miguel Cruz wrote: In short, I believe it's an OS rather than a PHP thing. time zones can be a messy and tricky beast. all the PHP functions rely on the underlying OS implementation of time zone information. sometimes this is controlled by the TZ environment variable, sometimes it is not. my solution was to extract as much info as reasonable from the zoneinfo database and manipulate it in PHP directly. the solution is not perfect, but is probably the best that can be done without more PHP access to the underlying zoneinfo implementation. my code (with all the time zone data zone IDs) is in PEAR: http://pear.php.net/package-info.php?pacid=57 thanks, baba -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] timezone problem
I had a similar issue, for a thing I'm doing for a Messageboard I am writing I need the timezones and offsets, so I compiled the best I could off different sites and info, and created a Mysql Table with all the timezones and offsets. there are duplicate offsets but since people know their TZ as different things depending where they live.

RE: [PHP] timezone problem
Here's what I was just thinking. This timezone seems too complicated and what do you guys think about me just displaying all the times in GMT and then allow the user to set to their local time by selecting a pulldown list of all the times GMT -11 to GMT +12. set local time to 1:10pm set local time to 2:10pm set local time to 3:10pm set local time to 4:10pm . . . They would have to change their settings once a year for day light savings but the good thing is I don't have to worry about tz anymore.

[PHP] timezone problem
I am trying to convert date/times to different timezones using putenv but I am having problems using the right TZ names.

Re: [PHP] timezone problem
I think these are system-specific. You'll probably have to check which time zone your machine understands. For instance, on this FreeBSD machine there are hundreds of them in /usr/share/zoneinfo but on other machines there are only a handful. In short, I believe it's an OS rather than a PHP thing. miguel On Mon, 20 May 2002, SP wrote: I am trying to convert date/times to different timezones using putenv but I am having problems using the right TZ names.

RE: [PHP] timezone problem
hi miguel i'm testing on a windows so not sure where the timezone info would be but what you are saying that if i port my app to a unix box then it would be easy to just add the missing timezones in /usr/share/zoneinfo, right? if that's the case then i could just test with pacific, eastern and mountain time for now. also, do you know if i store all my dates as GMT then when i convert to different timezones using putenv, will this take into account the daylight savings? -Original Message- From: Miguel Cruz [mailto:[EMAIL PROTECTED]] Sent: May 20, 2002 1:27 PM To: SP Cc: [EMAIL PROTECTED] Subject: Re: [PHP] timezone problem I think these are system-specific.

I'm not sure about the file format for those time zones - it seems to be some weird binary format. But hopefully your server will have a full complement available. also, do you know if i store all my dates as GMT then when i convert to different timezones using putenv, will this take into account the daylight savings?
