The TimeSpan
class represents a duration of time in milliseconds.
The TimeSpan
class represents a duration of time in milliseconds. In this
way, it is similar to the scala.concurrent.Duration
class. It is
mostly used in Lift APIs in similar positions as the Scala Duration
class (for example, in event scheduling).
Unlike in the Lift 2.x series, building a TimeSpan
with a Long
will not
have different behavior depending on the value passed. Any passed Long
will be used as a duration.
Prior to Lift 3.0, TimeSpan
was an amalgam of duration and joda
DateTime
, and allowed conversions between the two. As a result,
operational semantics were poorly defined and it was easy to call a method
that seemed like it should have simple duration semantics but run into
DateTime
semantics that made things more complicated instead.
Lift 3.0 mostly maintains API compatibility with the Lift 2.x series, but
introduces a series of deprecations to indicate places where dangerous
and potentially unclear behavior may occur. Lift 3.1 will maintain API
compatibility with all non-deprecated parts of the TimeSpan
API, but will
remove the deprecated aspects.
For deprecated years and month builders it handle an operations on duration field values. Then it could be used only in to-period implicit conversion.
