====time keyword====
This keyword evaluates to the [[harlowe:number|number]] of milliseconds passed since the passage
was displayed. Its main purpose is to be used alongside [[harlowe:Changer|Changer]]
such as [[harlowe:live|(live:)]] or [[harlowe:link|(link:)]]. ''%%(link:"Click")[(if: time > 5s)[...]]%%'', for instance,
can be used to determine if 5 seconds have passed since this passage was displayed,
and thus whether the player waited 5 seconds before clicking the link.

When the passage is initially being rendered, ''%%time%%'' will be 0.

''%%time%%'' used in [[harlowe:display|(display:)]] macros will still produce the time of the host passage, not the
contained passage. So, you can't use it to determine how long the [[harlowe:display|(display:)]]ed passage
has been present in the host passage.
