Ok, found this in internet:

"Time dummy is a variable which equals 1 for a given year and 0 for all other years. It allows to control for time-specific fixed effects i.e. shocks which impact is restricted to a given time-period, affects or panel units and are not controlled by other explanatory variables. " source: https://www.researchgate.net/post/Is_anyone_familiar_with_Time_Trends_vs_Time_Dummies

And: " Year effects (more simply known as “year dummies”" Source: https://www.dartmouth.edu/~ethang/Lectures/Class17/Always%20Control%20for%20Year%20Effects%20in%20Panel%20Regressions.pdf

So i think the use of Time dummies, are Time effects! But if time effects are always fixed I dont know.

No, time dummies dont imply time effectsOk, but you can use time dummiesfound this in internet:

So i think the use of Time dummies, are Time effects help to control for time variant unboserved stuff.!

No, time dummies dont imply time effects, but you can use time dummies to estimate time fixed effects.
