Overview

Checks for the use of ‘Time.zone=` method.

The ‘zone` attribute persists for the rest of the Ruby runtime, potentially causing unexpected behavior at a later time. Using `Time.use_zone` ensures the code passed in the block is the only place Time.zone is affected. It eliminates the possibility of a `zone` sticking around longer than intended.

Examples:

# bad
Time.zone = 'EST'

# good
Time.use_zone('EST') do
end
