This is my very first post to Pi Square. I am a Pi newbie and excited to learn, so please be gracious with my ignorance. So my question: I am working on an analysis template . I noticed that bod (beginning of day) is already a predefined function in the library, but what about something like boh('*'). I need to be able to round down to the last whole hour based on now. So for example, if it is 3:56 pm - I need 3pm. For 4:01pm, that would be 4pm. Thoughts? How do I get that value? Thanks in advance. Hope this is a easy one.
