Mobility Express stuck in DST

[Maurice_]

Greetings,

European Summer Time ended last Sunday (October 28), but our ME controller doesn't seem to have noticed and is now one hour ahead. The time zone is configured correctly (GMT+1 Amsterdam, Berlin, Rome, Vienna) and NTP is in sync. I can't find any settings related to DST in the Web GUI so it seems to handle that automagically. ME version is 8.8.100.0.

Any idea what's going on?

Hi Maurice,
we're having the same issue on our ME controllers as well. I also didn't found a right switch for this problem.
What helped was, changing the hours manually and refresh to check if NTP is still in sync. From now it seems to work in this way.

Hi Kenny,

I just tried that, but the time goes back to DST when I hit "Apply".

I really think this is a bug. Documentation says: "When you choose a time zone that uses Daylight Saving Time (DST), the controller automatically sets its system clock to reflect the time change when DST occurs." I tried several time zones, but it only works for a few:

GMT-8 (Pacific Time): Time is correct, now uses DST.

GMT-3 (Buenos Aires): Time is ahead 1 hour. ME uses DST, but there is no DST in Argentina at all.

GMT (London): Time is ahead 1 hour. ME uses DST, but DST ended on October 28.

GMT+8 (Hong Kong): Time is correct, there is no DST in China at all.

GMT+10:00 (Sydney): Time is behind 1 hour. ME doesn't use DST, but DST began on October 7.

Can someone reproduce this? Unfortunately I can't find any options to configure DST manually.

OK, a few days later the time is now correct for GMT-8, GMT-3, GMT, GMT+1 and GMT+8. GMT+10 is still behind one hour. So it seems that DST switching essentially works, but DST start and end dates in the firmware are wrong for many time zones. Cisco should fix this or make it user configurable.

Just for reference: I contacted Cisco about this back in March and they confirmed that it's a bug. A fix will be included in ME 8.10 (scheduled for August): https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvo87382
