Please let me repeat that DST changes are *not* an issue. If the system runs for many months, and has a condition timeout set that passes the DST change boundary, the condition *will* work correctly in the code as is. I don't know where you got the idea that DST changes are a problem, please rest ensured that they are no problem whatsoever, for the issue under discussion. The clock does *not* change when the time zone changes. The timeout will *not* be off by an hour.

Rejecting the patch as "won't fix".
