Dave Navarro, Jr. on "WP-CRON Execute at or after specific time"

How can I get a WP-CRON even to fire on or after 7am daily?

I tried the following:

wp_schedule_event( current_time('m-d-Y 07:00:00'), 'daily', 'nn_newsletter_event');

But it seams to use GMT and not local time as indicated in the codex.

I could put in 1:00:00 (since it's set up to run at noon), however it wouldn't take DST into account when it changes.
