Analyzing time is useless in TA?

From my own experience, time and price aren't related to each other in trading (talking about technical analysis). The only relation you can find between time and price is every X (month of the year, day, first 5 minutes of the hour, etc) a red/green/doji bar appears (which I haven't managed to find yet). So if I'm correct in saying that there is no relation between time and price, isn't time essentially a useless column (also making models that need correlation between time and price like ARIMA obsolete)? Someone please explain to me time series, I might've also got ARIMA wrong.
