I have a function that returns today's date/time at 00:00:00, e.g.,
2025-07-24T00:00:00, returned as seconds:
 proc start_of_day {} {
     clock scan "[clock format now -format %Y]-[clock format now \
             -format %m]-[clock format now -format %d]" -format "%Y-%m-%d"
}
 Is there a better way?

I am curious why a better way? It doesn't seem that heavy or slow.
However, you can make it more "robust". It is possible that on a Dec 31, 2024, you will get 2024-Jan-01T00:00:00 because you are treating 3 different time points as "now".  After the firs call for the year, the clock may switch to the next year.
