timestamp in events xml and sdp error

[Γιώργος Λαδιάς]

Hello to all,

In events xml there are timestamps in format:  <event timestamp="285442165" module="PARTICIPANT" eventname="ParticipantJoinEvent">. Can you plz tell me in what format is this timestamp because i want to read this xml with php to extract some info.

Also i have upgraded bbb from 1 to 1.1 and when i connect from everywhere i get the following error: Detected the following WebRTC issue: Error 1004: Failure on call (reason=Incompatible SDP). Do you want to try Flash instead? Nothing has changed in the settings with previous installation. Could you please help?

Thank you in Advance!

The timestamp in Unix EPOC time format.  You can convert it manually with

>  Detected the following WebRTC issue: Error 1004: Failure on call (reason=Incompatible SDP). 

Is your server setup for HTTPS?  Do you get this error in both FireFox and Chrome?

These are more development/setup related questions.  In the future, please post these questions to either bigbluebutton-dev or bigbluebutton-setup.  This mailing list, bigbluebutton-users, is more for end-user questions (such as "how do I share my webcam at larger resolution").

Regards,.. Fred

Thank you Fred. Next time i will post there..

For the first problem
it needs 13 digits but the timestamps have 9 or 10 digits. Do i have to add something in front of this timestamp? The meetings timestamp is 1520525040438 which gives correct results, but everything else timestamp have this format example:
 <event timestamp="1247395009" module="VOICE" eventname="ParticipantTalkingEvent"> timestamp 1247395009 gives this date: 7/12/2009, 2:08:23 PM

I think i'm missing something..

For the second problem
i have ssl enabled and the error occurs in both chrome and firefox.

Thanks in advance

Is your server running Ubunty 16.04 640-bit, try using the bbb-install script to configure your server, see

   https://github.com/bigbluebutton/bbb-install

provide it a hostname and e-mail address and it will configure the SSL using Let's Encrypt and configure BigBlueButton's components for you.

The event timestamps in the recording are in milliseconds using the
system "monotonic clock" and so are not realtime. To convert to
realtime, do this:

Find the first recording event in the file:
<event timestamp="177844875" module="PRESENTATION" eventname="SharePresentationEvent">

Then find the event you're interested in:
<event timestamp="178040606" module="WHITEBOARD" eventname="AddShapeEvent">

Take the two timestamps, and subtract:
178040606 - 177844875 = 195731

And take the timestamp from the recording ID:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-495727271951

and add:
495727271951 + 195731 = 495727467682

This is now a time in unix epoch time in milliseconds.
