Sometimes you need to calculate things based on current time (e.g. conditionally format tasks that are due, or show different text values for when the time is in the past or in the future). And sometimes those calculations are quite heavy.
What to do when you don’t need the precision of
Now() (which updates and triggers recalculations a few times per second), but
Today() is too coarse too?
Answer: make a less granular counter and depend on that. E.g., for minute-precision make a named formula
Coda will recalculate this formula every time
Now() changes (i.e. multiple times a second), BUT will not recalculate anything depending on this coarse timer as long as its [cached] value stays the same (i.e. for the entirety of a minute):
