This should have been in JIRA... Drop the mentality that you have to make a
case first to open a JIRA.
The actual process should be, if its any question about how FS works, if
you are right or wrong about it, file it as a JIRA. If its wrong we can
just close it........
If you want to send one email on the list to get some attention to your
jira for discussion its ok but really you want to have the entire thing
preserved there.
I pushed a patch (4bcf1d888a4629993923527c26d4dbc6dae5d470) that might be
related to your problem but now I have to wing it and use email where I get
200 emails a day and there is no tracking at all in email when it comes to
issues so you put more resources on me to try to remember to look for your
reply when we have a perfectly valid issue tracker system in place.....
If master works better, good, if not, try
git checkout 878a04715ae801ccd9587249240f5a6e4f16dd0e src/switch_time.c
and make install_core
All of this should be transposed back to JIRA by one of you.....
