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.
