<para>
<parameter>is_dst</parameter> can be set to 1 if the time is
during daylight savings time, 0 if it is not, or -1 (the default)
during daylight savings time (DST), 0 if it is not, or -1 (the default)
if it is unknown whether the time is within daylight savings time
or not. If it's unknown, PHP tries to figure it out itself. This can
cause unexpected (but not incorrect) results.
</para>
<para>
Some times are invalid if <parameter>is_dst</parameter> is set to 1. If
DST is enabled in e.g. 2:00, all times between 2:00 and 3:00 are invalid
and <function>mktime</function> returns an undefined (usually negative)
value. Some systems (e.g. Solaris 8) enable DST at midnight so time 0:30
of the day when DST is enabled is evaluated as 23:30 of the previous day.

<parameter>is_dst</parameter> was added in 3.0.10.

<function>mktime</function> is useful for doing date arithmetic
and validation, as it will automatically calculate the correct
