clock change

Hi

We had a AIX box built last year but was set to the correct GMT time, but using DST time zone. In march this year the clocks went forward without issues. (if I remember a couple of weeks early due to the DST zone)

This year we decided to change the clock to the correct time zone before the clock change at the weekend.

Therefore the timezone was set to BST, however this weekend (28th October) the clock didnt change.

Now we dont really know AIX and have a third party do all the work. What we have been told is there is some file that needs changing and was missed when they set the clock to BST. But one of the questions is why didnt the clocks adjust automatically when set to DST on Sunday.

My next question is

We have now been told that to change the clock to BST correct time, we have to stop our applications/stop oracle and reboot the server so it will automatically change when the clocks jump forward/backwards.

IDATE(3)								 1								  IDATE(3)

idate - Format a local time/date as integer

SYNOPSIS
int idate (string $format, [int $timestamp = time()]) DESCRIPTION
Returns a number formatted according to the given format string using the given integer $timestamp or the current local time if no time- stamp is given. In other words, $timestamp is optional and defaults to the value of time(3). Unlike the function date(3), idate(3) accepts just one char in the $format parameter. PARAMETERS
o $format - The following characters are recognized in the $format parameter string +------------------+---------------------------------------------------+ |$format character | | | | | | | Description | | | | +------------------+---------------------------------------------------+ | | | | B | | | | | | | Swatch Beat/Internet Time | | | | | | | | d | | | | | | | Day of the month | | | | | | | | h | | | | | | | Hour (12 hour format) | | | | | | | | H | | | | | | | Hour (24 hour format) | | | | | | | | i | | | | | | | Minutes | | | | | | | | I (uppercase i) | | | | | | | returns 1 if DST is activated, 0 otherwise | | | | | | | | L (uppercase l) | | | | | | | returns 1 for leap year, 0 otherwise | | | | | | | | m | | | | | | | Month number | | | | | | | | s | | | | | | | Seconds | | | | | | | | t | | | | | | | Days in current month | | | | | | | | U | | | | | | | Seconds since the Unix Epoch - January 1 1970 | | | 00:00:00 UTC - this is the same as time(3) | | | | | | | | w | | | | | | | Day of the week ( 0 on Sunday) | | | | | | | | W | | | | | | | ISO-8601 week number of year, weeks starting on | | | Monday | | | | | | | | y | | | | | | | Year (1 or 2 digits - check note below) | | | | | | | | Y | | | | | | | Year (4 digits) | | | | | | | | z | | | | | | | Day of the year | | | | | | | | Z | | | | | | | Timezone offset in seconds | | | | +------------------+---------------------------------------------------+ o $timestamp - The optional $timestamp parameter is an integer Unix timestamp that defaults to the current local time if a $timestamp is not given. In other words, it defaults to the value of time(3). RETURN VALUES
Returns an integer. As idate(3) always returns an integer and as they can't start with a "0", idate(3) may return fewer digits than you would expect. See the example below. ERRORS
/EXCEPTIONS Every call to a date/time function will generate a E_NOTICE if the time zone is not valid, and/or a E_STRICT or E_WARNING message if using the system settings or the $TZ environment variable. See also date_default_timezone_set(3) CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.1.0 | | | | | | | Now issues the E_STRICT and E_NOTICE time zone | | | errors. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 idate(3) example <?php $timestamp = strtotime('1st January 2004'); //1072915200 // this prints the year in a two digit format // however, as this would start with a "0", it // only prints "4" echo idate('y', $timestamp); ?> SEE ALSO
