Could not calibrate time offset: Time is out of dual 32-bit range

While trying to run urg_node with Hokuyo UST-05LA (May, 2016), recieving the following error:

[ INFO] [1587784386.134593468]: Starting calibration. This will take a few seconds.
[ WARN] [1587784386.134724427]: Time calibration is still experimental.
[FATAL] [1587784386.152248769]: Could not calibrate time offset: Time is out of dual 32-bit range

log file: /root/.ros/log/ad0866ba-86a2-11ea-b3c1-5eb80ed6475f/urg_node_back-2*.log

Launch node is the following:

<node name="urg_node_back" pkg="urg_node" type="urg_node" output="screen">
    <param name="ip_address" value=""/>
    <param name="ip_port" value="10941"/>

    <param name="serial_baud" value="115200"/>

    <param name="calibrate_time" value="true"/>

    <param name="topic_name" value="/scan_2"/>
    <param name="skip" value="1"/>
  </node>

I'd like to point out, when calibrate_time set to false, node seem to work. Error appears only when it's set to true.

I suspect, it's also related to 23, comment, but it seems like it has been fixed in 35, pull. Any ideas?

Btw, I'm having the same type of Hokuyo UST-05LA but manufactured in (May, 2018). calibrate_time = "true" running has no problem and it works.

sudo picocom /dev/ttyACM1 output:

It's not a protocol issue, since PROT:SCIP 2.0.
