Product / project / scrum guy here. Logging time won't make sense unless each ticket is one person working on it at a time. The moment it becomes teamwork (like asking someone else for their thoughts on an idea) the value of time is meaningless.

People are also useless at estimating time in advance, but pretty great with throwing a story-point number on a given story with the right guidance. Please feel free to schedule me in with your uneducated upper management. They're about to lose value.

Many companies use Jira tickets to track employee time, instead of having a separate time tracking system.

This creates a situation where everyone is searching for tickets to make up for their daily 8h.

Same in the company I work at, but only for IT employees. It's fine as long you have over 80% of the monthly hours in you contract tracked. Definitely not used for micromanagement. I myself find it useful for seeing inefficiencies in what I do and ensuring I actually go home.

It's handy for charging clients for development work specific to them.
