Disruptions In Time by ML Thompson Hey there.
I found this story through our scavenger hunt for a time travel fic.
"Really, Ms. Lane. It is imperative that we leave now. Time is of the essence."
"What's going on?"
"Tempus escaped from a future time and went into the past. From what I have been able to tell, he must have gone back to a time shortly after Clark began working at the Daily Planet because when I was searching for changes in history, I discovered that shortly after that time, you were offered a job anchoring at LNN."
"I was never offered a job anchoring at LNN."
"Exactly."
Lois thought for a moment. "Well, nothing seems to have changed as a result."
"Ms. Lane, I've been back there. The reason nothing has changed is because you are still thinking about it. But you are to get back to them first thing in the morning. I tried talking to you and to Clark Kent, stressing the importance of having you turn down this job. However, you don't believe me and Clark doesn't think he has any right to interfere."
I loved how the older Lois convinced the younger Lois that Clark was someone worth pursuing. She showed her the future and somehow Clark managed to not reveal his secret in the process.
Also the future without Clark in it was really dark and I'm so glad younger Lois saw the light in time.
