Filter for relative time comparison

Today we've released a new option to filtering timestamps - the ability to compare a timestamp to the current time, in order to e.g. find users that signed up "in the last 2 hours". This filter opens up the possibility of creating Policies that flag users that signed up and then quickly did something suspicious, like creating 10 new content posts. Seeing high velocity abuse from new accounts like this is very common across multiple types of services.
