[ date->difference ]
[Date->Difference] determines the duration time between two Lasso dates. Requires a date type as the parameter.
The difference between the two dates is calculated by subtracting the Lasso date object from the date parameter. The output is a Lasso duration in hh:mm:ss format.
Optional parameters may be used to ouput a specified integer time value instead of a duration: -Millisecond, -Second, -Minute, -Hour, -Day, -Week, -Month, -Year. Lasso rounds to the nearest integer when using these optional parameters.

date('2011-02-21 08:00:00')->difference(date('2011-02-23 08:00:00'))
date('2011-02-21 08:00:00')->difference(date('2011-02-23 08:00:00'), -hour)Result
