You'll need to always run it from Action Chains, though.

Some more detail to use Action Chains to make this automatic.

• Create a chain with 2 actions:
  1. send the selected book(s) by email (Calibre actions / Connect share / Email to ...)
  2. set the custom date/time column to today (Single Field Edit of your custom column).
• If you wish, give the chain a keyboard shortcut.
• Then use the chain to send your book(s) instead of the standard Connect / share option.

If you need help, ask in the Action Chains thread.
