Bad argument to randomseed

[ncul777]

I'm developing some lua code on OpenWrt 22.03 (latest for my device) which has Lua 5.1.5. I downloaded the luaunit.lua (version 3.4) file to my device, but when running I got the error

luaunit.lua:247: bad argument #1 to 'randomseed' (integer expected, got number)

It seems that the line below returns a number that is bigger than a 32 bit signed integer:
math.floor(os.clock()*1E11)

The initial value of the os.clock() is several hundred ms e.g. 0.07.
Suggestion - use modulus to force range within 32 bit range (and this worked for me)
math.floor((os.clock()*1E11) % 2147483647)

I noticed there was a related PR here
