[CoovaChilli] Wrong Timestamp on Radius Accounting messages

We've been using CoovaChilli for a while now and bumped into a weird
issue where users get disconnected shortly after being successfully
logged on. They browse the internet and then simply get logged out.
( The current setup was done by three people that no longer work here
and I've been learning about Chilli as quickly as possible, but I'm
still in the dark regarding a lot of details. )
The hotspot controller runs on an embedded linux device on each site,
which comunicates to a freeradius authorization+accounting server which
then feeds off our databases, captive and management portals.
I'm trying to trace why users get disconnected shortly after logging in
and was unable to find a reason. Looking directly at radius accounting
logs I found some suspicious details:
Mon Apr 8 20:37:13 2019
ChilliSpot-Version = "1.3.0"
Attr-26.14559.10 = 0x00000001
Event-Timestamp = "Jan 22 2015 11:23:15 AEST"
User-Name = "141_125758"
Acct-Status-Type = Start
Acct-Session-Id = "5cab22ef0000004e"
Framed-IP-Address = 10.1.0.13
NAS-Port-Type = Wireless-802.11
NAS-Port = 78
NAS-Port-Id = "00000078"
Calling-Station-Id = "38-53-9C-D2-A5-1A"
Called-Station-Id = "78-8A-20-7D-EA-3C"
NAS-IP-Address = 10.1.0.1
NAS-Identifier = "170_1_waves12221_4"
WISPr-Location-ID = "isocc=,cc=,ac=,network=Waves,"
WISPr-Location-Name = "xxxxxx"
FreeRADIUS-Acct-Session-Start-Time = "Apr 8 2019 20:37:13
Tmp-String-9 = "ai:"
Acct-Unique-Session-Id = "ddd0d4ae7a43b176b46ab68a10c0f37d"
Timestamp = 1554719833
Now... I'm not sure that this is wrong 2015 Timestamp is what's causing
users to get logged off but it doesn't seem right.
Can anyone tell me how to trace back where this wrong timestamp is
being generated? Would it be the Controller where Chilli runs, some
internal Chilli clock or even the end user device?
All ideas will be most appreciated.
