To save space, Mbient labs records time in seconds since start of recording. When the appropriate app exports the data time is represented as seconds since 1970; basically linux epochs. This is easier to parse, see the '[lubridate](https://lubridate.tidyverse.org/)' R package. If the CSV file contains errors or complex quote in quote or strings with many special characters like URLs the problem becomes more complicated. When I analyze the data some functions can not work with class time date so I am forced to convert time date back to seconds. This may not apply to all statistical analysis tools but they all internally hold time date as something very close to a double or integer than a character string.
