Yes, but if you want to learn R (or relearn R) it would be better for you to decompress the code. You know what b looks like so add the next step. If you want to be able to see the original then save the output to another data frame. New_df <- b %>% mutate(Dtime = paste(Sys.Date(), Dtime), Dtime = as.POSIXct(Dtime))
What do you have now? Then add the next pipe %>% and code until the next %>%. When you look at the dataframe after reshape() it will be very obvious, though if you still have questions please ask.
