I found out that I can only set an offset

<programming> An index or position in an {array}, {string}, or
	block of memory usually a non-negative {integer}.

	E.g. the {Perl} function splice(ARRAY, OFFSET, LENGTH, LIST)
	replaces LENGTH elements starting at index OFFSET in array
	with LIST, where offset zero means the start of the array.

	For an {Intel x86} processor with a {segmented address space}
	the offset is the position of a {byte} relative to the start
	of the segment.

in my session

<networking> 1. A lasting connection between a user (or user
	agent) and a {peer}, typically a {server}, usually involving
	the exchange of many packets between the user's computer and
	the server.  A session is typically implemented as a layer in
	a network {protocol} (e.g. {telnet}, {FTP}).

	In the case of protocols where there is no concept of a
	session layer (e.g. {UDP}) or where sessions at the {session
	layer} are generally very short-lived (e.g. {HTTP}), {virtual}
	sessions are implemented by having each exchange between the
	user and the remote host include some form of {cookie} which
	stores state (e.g. a unique session ID, information about the
	user's preferences or authorisation level, etc.).

	See also {login}.

	2. A lasting connection using the {session layer} of a
	networking protocol.

in my ISP

1. {Internet Service Provider}.

	2. {Instruction Set Processor}.

's MySQL server, not a timezone. So I am left with the
task of setting the offset, which will vary, depending on whether
or not DST

is in effect.

Is there a way of discovering, from a PHP script is we are in DST
or standard

<standard> Standards are necessary for {interworking},
	{portability}, and {reusability}.  They may be {de facto
	standards} for various communities, or officially recognised
	national or international standards.

	{Andrew Tanenbaum}, in his Computer Networks book, once said,
	"The nice thing about standards is that there are so many of
	them to choose from", a reference to the fact that competing
	standards become a source of confusion, division,
	obsolescence, and duplication of effort instead of an
	enhancement to the usefulness of products.

	Some bodies concerned in one way or another with computing
	standards are {IAB} ({RFC} and {STD}), {ISO}, {ANSI}, {DoD},
	{ECMA}, {IEEE}, {IETF}, {OSF}, {W3C}.

In {object-oriented programming} sending a message to an
	{object} (to invoke a {method}) is equivalent to calling a
	{procedure} in traditional programming languages, except that
	the actual code executed may only be selected at run time
	depending on the {class} of the object.  Thus, in response to
	the message "drawSelf", the method code invoked would be
	different if the target object were a circle or a square.

if(date("I") == 1)
{
//daylight saving time
}
else
{
//not daylight saving time
}

Whether this is accurate (in light of the recent change in the
definition of DST) is up to your server.

Do not forget to set date.timezone to client
<programming> A computer system or process that requests a
	service of another computer system or process (a "{server}")
	using some kind of {protocol} and accepts the server's
	responses.  A client is part of a {client-server} software
	architecture.

	For example, a {workstation} requesting the contents of a file
	from a {file server} is a client of the file server.

timezone before checking that.

yeah, that is the problem, my ISP will only allow setting the
timezone offset, not the timezone.

I will get around that.
