   BTW there is a (fairly nasty) workaround to cast to an integer and do the math that way
   
   So for example, rather than 
   
   ```sql
   select now() - interval '10 minutes'
   ```
   
   You can write something like
   
   ```sql
    select CAST(now() as bigint) - 10*60*(1000000000) 
   ```
   
   Which is definitely not very pretty 😢  but it does work
