I don't know when it changed, but in net-snmp 5.7.2 running your original
code results in the desired values on the wire:

37.1.7.1.6.1610670080.4294967295.4294967295=146
37.1.7.1.7.1610670080.4294967295.4294967295=131
37.1.7.1.14.1610670080.4294967295.4294967295=1
37.1.7.1.15.1610670080.4294967295.4294967295=1
37.1.7.1.13.1610670080.4294967295.4294967295=4

Get your SQL database under version control now!
Version control is standard for application code, but databases havent 
caught up. So what steps can you take to put your SQL databases under 
version control? Why should you start doing it? Read more to find out.
