Hi there
Since glob is actually a part of the core - Are you absolutely sure
that you're running PHP > 4.3

Hi Louis,
Yes, I have read that glob is only available for PHP > 4.3 and I am
using version 5.2.1.7
# /usr/local/bin/php -v
PHP 5.2.17 (cli) (built: Feb 16 2011 15:41:35)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies
with Zend Optimizer v3.3.9, Copyright (c) 1998-2009, by Zend Technologies
# /usr/local/bin/php globtest.php
Fatal error: Call to undefined function glob() in
/usr/local/apache2/htdocs/hrms/globtest.php on line 2
I have read somewhere that it could be connected to glibc, not I have
no idea how to fix that. Anyone ?

Yesterday I yum installed these:
glibc-common.i386 2.3.4-2.54
glibc.i686 2.3.4-2.54
glibc-headers.i386 2.3.4-2.54
glibc-devel.i386 2.3.4-2.54
And about ten minutes ago I recompiled PHP with identical configure
options as before. And this time the glob function is inside PHP.
Phew.
Hopefully someone else will benefit from this post.

Hi,
I want the code to return the timestamp for the current time in
Singapore. The format command returns different result if the 'U' for
timestamp is specified. It also returns the same (wrong) result for
DateTime::getTimestamp() as well.
The clients are booking entry into a place at a specific time, for
example 7am in Singapore on the 12 April. Clients can book right up to
the entry time (if there is space available). I want to make sure they
are not trying to book in the past.
The booking system is in the UK but clients can book from anywhere. I
cannot rely on them having the right time on their systems (or being in
the right place). Plus this would mean relying on client supplied data,
which is a no-no ;)
I have previously used a gmt offset, which was good enough as there are
not that many people who book close to the entry time. But now its time
to improve this and use proper time zone info which can change without
my input.
If no-one can find a problem with my code I will submit it as a bug.
Thanks
Ian

May I suggest including the timezone in your date format (O or e)? It may show
the two date strings to be equivalent.

Timestamps (the integer value) do not hold the timezone data.
Internally, the value represents a number of milliseconds from a point
in time.
So saying "timestamp for Asia/Singapore" isn't right. It is just "Timestamp".
The following script (http://pastebin.com/0MQAaYUq) may show you in a
more concrete way ...
<?php
$a_Times = array(
'now',
'2011-03-27 00:59:59',
'2011-03-27 02:00:00',
);
// Create Timezone objects
$a_Timezones = array(
'Singapore' => new DateTimeZone('Asia/Singapore'),
'NewYork ' => new DateTimeZone('America/New_York'),
'London ' => new DateTimeZone('Europe/London'),
'UTC ' => new DateTimeZone('UTC'),
);
foreach($a_Times as $s_Time) {
echo 'Time : ', $s_Time, PHP_EOL;
// Create datetime objects
$a_DateTimes = array();
foreach($a_Timezones as $s_Timezone => $tz_Timezone) {
$a_DateTimes[$s_Timezone] = new DateTime($s_Time ,
$tz_Timezone);
}
// Print the date
foreach($a_DateTimes as $s_Timezone => $dt_DateTime) {
echo
'Current time in ', $s_Timezone, ' : ',
$dt_DateTime->format(DateTime::RSS),
' Offset : ', str_pad($dt_DateTime->getOffset(), 6, '
', STR_PAD_LEFT),
' Timestamp : ', ($i_Timestamp =
$dt_DateTime->getTimestamp()),
' Local : ', date(DateTime::RSS, $i_Timestamp),
PHP_EOL;
}
echo PHP_EOL;
}
?>
outputs (http://pastebin.com/mETSbR7h) ...

Getting the the timestamp for a DateTime object will return the
timestamp appropriately converted to the local timezone.
If you don't want to lose the timezone, then don't use the timestamp.
This, of course, is an issue if you want to use datetimes in a DB.
In these instances, converting the datetime to UTC and storing the
timezone separately is certainly one option.
If you are using SQL Server 2008, then there is a column type of
DATETIMEOFFSET which is a datetime column with Timezone and
100nanosecond accuracy, so you can store and use datetimes like ...
2007-05-08 12:35:29.1234567 +12:15
Which is a pretty accurate.
I guess there is some difference in logic between knowing the timezone
and the timezone offset.
I found the talk by Derick Rethans very useful : (looking for this but
can't find it any more. The link to it is
http://www.phparch.com/2009/08/dont-miss-todays-webcast-on-date-manipulation/
A book is also available :

Hi,
Found the problem:
Unix timestamps are a moment in time and so timezones have no influences
on them. They count the number of seconds since 1970-01-01 00:00 *UTC*
See: http://en.wikipedia.org/wiki/Unix_time
So the timestamp will always be the same no matter which timezone.
I will use by workaround to get the expected timestamp for use in
comparisons.
Regards
Ian

OK gang, to spew a single line from a file of fortune cookies, I
