The configuration is Openfire 3.7.1 with Spark 2.6.3.
I make you an example: I’m out of office.
A collegue sends me a message with Spark at 10:30am.
I arrive at office at 11:45am and I power on my PC.
After the login I see the popup with the message of my collegue with the right time (10:30am).
If I close the popup and I open it again, I see the same message of my collegue with the time modified to 11:45am (the time when I power on my PC).
Spark changes the time of the message, when I close the popup with the message.
No problem if I’m logged in my PC, also if it’s in suspend mode.
The problem is only when the PC is switched off: I have made some tests with other users and other PCs, but the problem is the same.
Thank you in advance for your support.
