Filterrows, date column by comparing gte "now-24h"

Hi , how can we filterrows, date column by comparing gte "now-24h" ,
instead of "timefilter column="time" from="now-24h" to="now"

eg.
| filterrows fn={ getCell "time"| gte "now-24h"}
is not working

Could you provide some more details? Maybe frame your question around one of the sample data sets that kibana ships with. Screen shots and usecase would really help
