Wrong Boot Time with Linux Agent on Synology NAS

[janstalhut]

Server Info (please complete the following information):

• OS: Debian 12
• Browser: Firefox
• RMM Version (as shown in top left of web UI): 0.19.3

Installation Method:

• [X] Standard
• [ ] Standard with --insecure flag at install
• [ ] Docker

Agent Info (please complete the following information):

• Agent version (as shown in the 'Summary' tab of the agent from web UI): 2.8.0
• Agent OS: Linux: Synology DiskStation Manager (DSM)

Describe the bug The boot time is displayed incorrectly, it always says "55 years ago", also after a fresh Synology reboot

I have tried various Synology models from different generations: All of them seem to be affected by this problem:

• Devices with x86_64 and ARM processors
• Older and newer devices, large and small devices (e.g. DS216se, DS1817+)
• Various Linux kernels: 3.x, 4.x, 5.x
• Various (current) DSM versions: 7.1 and 7.2

To Reproduce Steps to reproduce the behavior:

1. Using the Linux Install Script to install the Agent on Synology via SSH
2. The column Boot Time on TRMM shows "55 years ago"

Expected behavior Display of the correct boot time, like other Linux devices.

Additional context Unfortunately, I don't know how the agent determines the boot time. However, if I use the "uptime" command on one of the Synology systems, I get the correct time at which the system started.

If I can somehow help solve the problem with a debug log or something similar from the agent, please let me know.

can you run the following command as root on the synology and paste output, make sure to redact urls and tokens:

tacticalagent -m checkin -log debug -logto stdout
