Is it possible to compare a timestamp in a record to now to compute how long ago it occurred (which would then let you filter out things that are, for example, 30 days older than the current moment)? I know you can use between to build a custom column to note if a record is within a certain range, but you have to explicitly list the date stamp.
Hi @nutron
Currently the Custom Expressions doesn’t support time functions:
