Are the expressions "cursed time," "harsh months," "metallic time," and "time of armed wheat stalks" considered a cursing of time?

What is forbidden by Islamic law is to curse time and to find fault with it in a manner of reproach and discontent. As for describing it with what it contains in a purely informative way, that is not prohibited. The phrase "in this cursed time" is a cursing of time. As for "long, harsh months," it could be either a cursing or a purely informative statement.
