I am reading a string that has the following form: "2020-08-26_05:15:01" I want to convert the string to a date-time variable. I tired: x <- "2007-02-01_10:10:30"
That underscore is what's causing your problems. If it needs to stay in there because you have a bunch of them in htat format then you need to add the appropriate format string.

x <- as.POSIXct(x,tz=Sys.timezone()) x but this did not work; the time portion was ignored. I suspect the problem is the _ between the date and time, but I don't know how to account for this character in the string. I hope someone can tell me how to read the string as a date time constant.
