invitation from Lotus shows wrong time
Hi, I have just moved to Win10. Prior to this I received invites from users on Lotus Notes which arrived showing the right time. They now arrive starting an hour late. This .ics file arrived yesterday & loaded at 16:00 instead of 15:00: "BEGIN:VCALENDAR X-LOTUS-CHARSET:UTF-8 VERSION:2.0 PRODID:-//Lotus Development Corporation//NONSGML Notes 8.5.3//EN_S METHOD:REQUEST BEGIN:VTIMEZONE TZID:GMT BEGIN:STANDARD DTSTART:19501029T020000 TZOFFSETFROM:+0100 TZOFFSETTO:+0000 RRULE:FREQ=YEARLY;BYMINUTE=0;BYHOUR=2;BYDAY=-1SU;BYMONTH=10 END:STANDARD BEGIN:DAYLIGHT DTSTART:19500326T020000 TZOFFSETFROM:+0000 TZOFFSETTO:+0100 RRULE:FREQ=YEARLY;BYMINUTE=0;BYHOUR=2;BYDAY=-1SU;BYMONTH=3 END:DAYLIGHT END:VTIMEZONE BEGIN:VEVENT DTSTART;TZID="GMT":20150909T150000 DTEND;TZID="GMT":20150909T153000 TRANSP:OPAQUE DTSTAMP:20150903T150816Z SEQUENCE:0 ATTENDEE;ROLE=CHAIR;PARTSTAT=ACCEPTED;CN="
but this arrived a few weeks ago and started at the right time (ie 15:00): "BEGIN:VCALENDAR X-LOTUS-CHARSET:UTF-8 VERSION:2.0 PRODID:-//Lotus Development Corporation//NONSGML Notes 8.5.3//EN_C METHOD:REQUEST BEGIN:VTIMEZONE TZID:GMT BEGIN:STANDARD DTSTART:19501029T020000 TZOFFSETFROM:+0100 TZOFFSETTO:+0000 RRULE:FREQ=YEARLY;BYMINUTE=0;BYHOUR=2;BYDAY=-1SU;BYMONTH=10 END:STANDARD BEGIN:DAYLIGHT DTSTART:19500326T020000 TZOFFSETFROM:+0000 TZOFFSETTO:+0100 RRULE:FREQ=YEARLY;BYMINUTE=0;BYHOUR=2;BYDAY=-1SU;BYMONTH=3 END:DAYLIGHT END:VTIMEZONE BEGIN:VEVENT DTSTART;TZID="GMT":20150722T150000 DTEND;TZID="GMT":20150722T153000 TRANSP:OPAQUE DTSTAMP:20150721T125212Z SEQUENCE:0 ATTACH:CID:1__=0FBBF41ADFD66BC08f9e8a93df938690918c0FB@ ATTENDEE;ROLE=CHAIR;PARTSTAT=ACCEPTED;CN="
I don't see too much difference apart from the date. Is this a Win10 time zoning issue? As far as I'm aware, I'm in UK (Dublin, Edinburgh, Lisbon, London) with time and daylight saving set automatically. Region is UK.
I have had this before but it was a Lotus notes problem that time round, whereas there's been no change to the Notes server recently.
Please let me know if you need any more information - it's all far too deep for me to understand.
Thanks & regards Milkfloat

Thunderbird uses the Computer settings. Located a link on Windows 10 Time and area zone settings:
Hi, as per reply to note I am using correct local settings (UK time zone, daylight saving etc). Have tested similar event invitation to user on Outlook and invite to there created an event at the correct time (ie the same time as Notes). This makes it Thunderbird that stands out from the crowd.
Only other change is that Thunderbird moved to 38.2 on 31 Aug 15 and problems might be since then, not since W10 upgrade.
You probably have checked that Lightnings timezone setting are right.
Just check this: Open tools / error console and write: Date () Does it give you the right time?
Yes, Date() returns the same time as shows on the task (or is it tool) bar at the bottom of the screen.("15:37:04 GMT+0100 (GMT Standard Time)" in this case).
I'm still curious about timezone settings in Lightning if they are the same as in Win 10 (see https://support.mozilla.org/en-US/questions/1081169 )
I've just sent an invite to a Notes account & the event has been created at the right time in Notes.
It looks (to my untutored eye) as if the Tbird/ Lightning processor doesn't like the way Notes defines the timezone + daylight offset.
As far as i know, Lightning cannot set its own timezone. have I missed something?
Whereas my time zone, as in (new Date).toUTCString() comes out an hour different - it shows 15:59 when date() shows 16:59. .. but my Win10 timezone is (UTC) Dublin, Edinburgh, Lisbon, London, and that's right for where I am.
So, back to where I was: the date&time time is correct, the timezone is correct, but LIghtning calculates a wrong time from it. is there a simple solution to this?
try tools / calendar / general and set timezone

UTCString should show GMT without DST. Thats the time to adjust different TimeZones and DST against. Mine would show the same as yours. While Date would show GMT+2 (Stockholm)
OK thanks Gnospen, understand the UTCstring now. Timezone in Lightning (Tools Options Calendar is "Europe/London"), which is also correct. I'm still lost as to the cause. PC time zone is correct, Clock time is right, Date() provides right time but invites received create events an hour out
I think this is a Lightning bug. Please post this as a bug. Login / register : https://bugzilla.mozilla.org/index.cgi?
Give info : OS, version of thunderbird and Lightning and whether you use google calender etc. State what occurs.
