I send it to my internal mail system hosted on a Synology NAS. The account is a SMTP with authentication but without encryption.
Maybe the reason emailing didn't work is that the provider has establishd SSL/TSL for client access... and you can't set up security acces for SMTP nor the port to use.
An other reason could be that the provider identified the mail as spam and dropped it.

My device states like

Firmware Version:	3.16.9 Build 150409 Rel.60640n
Hardware Version:	WA901ND v3 00000000

Did anyone find a resolution to this? We have a large number of these devices which yesterday suddenly all started reporting the wrong uptime. The behaviour is exactly the same as that described above - the uptime is correct until about 47 seconds after booting up and then changes to around 196 days.
