Hi, all,
i’m trying compare with timex variables,
but i don’t know why this code work like that..
dts = Timex.parse!( "2019-01-01T00:00:00.000Z", "{ISO:Extended:Z}" )
now = Timex.parse!( "2019-01-01T00:00:00.100Z", "{ISO:Extended:Z}" )
dt = Timex.shift( dts, seconds: 5 )
if ( dt <= now ) do
raise ( "why? dt already shift seconds... dt[#{ inspect dt }] now[#{ inspect now }]" )
else
:ok
end
I thought that such a comparison should be the opposite result…
anyone can help me to understand this? thanks

You need to use
Timex.compare/2/3instead ofKernel.<=/2.Also Liked

I tend to always use the regular comparison operators against
0.This does match semantics very well.

The built in comparison operators aren’t the right tool for this job. You probably want to use Timex.compare/3.
For an explanation of why this is the case you might find this useful. Especially this quote:
