How to change the label by time?

Hi, I would like to change the label by time.

In detail, items are generated by source with labels(duniform 1 to 4).

When the item was transported into the rack, it begins to count the time how long the items stay in the rack.

Every 24 hours past, the label of the item will plus 1 ,until it reach 4 (the maximum).

Please help me to solve it. Thanks a lot!

Hi @Briankuo! Have you looked at this question?

You could also use process flow and a date/time source to change the label or use some custom code to check if the token label should be changed. It might be helpful to post a model if you want more specific help!

An alternative to creating events to change the label over time is to just calculate the age when you need it:

Math.floor((time()-stats_lastmovetime(item).value)/days(1))

int numdays =(time()-stats_lastmovetime(item).value)/days(1);
return Math.min(4,numdays);

Which you may be able to add as an expression in a list replacing 'item' with 'value'.
