I have multiple data sets (hundreds) with time series data like this:

Each data set has a unique datetime value (Trigger Time) that is treated as a comment. Each data set also has a Time variable indicating the time that has passed since the datetime in Trigger Time. What I want to do is calculate the datetime for each observation so that I can graph the data as a time series using R Statistics. Is there a way to accomplish this? Merging the datasets and appending the comments does not necessarily have to be done in R.
I have imported the data from all files in R Statistics using the list.files and llply functions, as suggested by Matt Bogard in this blog post. Here is a link to the data sets I use in the example below.
require(plyr)
filenames <- list.files(path = "C:/Users/bys/Desktop/log-trykk-vinkelrett/data-test/", full.names = TRUE)
import.list <- llply(filenames, read.csv)
Here is a link the output from import.list using dput.
I think I then need to do something similar to what learnr is suggesting here, but so far my attempts at extracting Trigger Time and adding a new variable with Trigger Time for each observation have been unsuccessful.
Solving the problem with Open Refine causes the program to crash every time I try to load all the data sets. R may not be the best tool for processing text files, but I don't have any experience with Python, Ruby or similar languages.
