Correlation or Subscription Value
The
subscriptionvar
item specifies the correlation or subscription value.
The value can be one of the following:
datevar
datetimevar
stringvar
booleanvar
longvar
floatvar
doublevar
bindvar
The syntax for
datevar
and
datetimevar
are as follows:
$date(year,month,day,[,GMT offset]) $datetime(year,month,day,hour,minute,second,millisecond[,GMT offset])
Note that the
$date()
and
$datetime()
functions have an optional GMT timezone offset. This timezone offset is expressed as a plus sign (+) or a negative sign (-) followed by four digits, within double quotes. For example, to specify GMT minus eight hours and 30 minutes, use
"-0830"
As another example, use
"+0200"
to specify GMT plus 2 hours.
