RchivalTag package date - r

Question

I am trying to use the RchivalTag package in R and I am having issues with the date and time. Whenever I try to use read_histos() it gives me the following error:
hist_dat_1<- read_histos(Georgia)
Warning: 598 parsing failures.
row col expected actual
1 -- date like %H:%M:%S %d-%b-%Y 2009-02-23 00:00:00
2 -- date like %H:%M:%S %d-%b-%Y 2009-02-23 06:00:00
3 -- date like %H:%M:%S %d-%b-%Y 2009-02-23 12:00:00
4 -- date like %H:%M:%S %d-%b-%Y 2009-02-23 18:00:00
5 -- date like %H:%M:%S %d-%b-%Y 2009-02-24 00:00:00
... ... ........................... ...................
See problems(...) for more details.
Error in .fact2datetime(as.character(add0$Date), date_format = date_format, :
date concersion failed! Please revise current'date_format': %H:%M:%S %d-%b-%Y to 2009-02-23 00:00:00
Current date/time class:
class(Georgia$Date)
#[1] "POSIXct" "POSIXt"
I have changed the date and time format to:
format(Georgia$Date, format = "%H:%M:%S %d-%b-%Y")
But I am still getting the error message. If anyone is familiar with this package, help would be greatly appreciated

This is a difficult one without reproducible data, but we can actually replicate your error using one of the package's built-in data sets:
library(RchivalTag)
hist_file <- system.file("example_files/67851-12h-Histos.csv",package="RchivalTag")
Georgia <- read.csv(hist_file)
This reads the histogram data in as a data frame, which seems to be the stage you are at. We will, however, change the format to POSIXct standard date-time representation.
Georgia$Date <- strptime(Georgia$Date, "%H:%M:%S %d-%b-%Y")
Georgia$Date <- as.character(Georgia$Date)
Now when we try to read the data we get:
read_histos(Georgia)
#> Warning: 34 parsing failures.
#> row col expected actual
#> 1 -- date like %H:%M:%S %d-%b-%Y 2012-02-01 08:10:00
#> 2 -- date like %H:%M:%S %d-%b-%Y 2012-02-01 12:00:00
#> 3 -- date like %H:%M:%S %d-%b-%Y 2012-02-02 00:00:00
#> 4 -- date like %H:%M:%S %d-%b-%Y 2012-02-02 12:00:00
#> 5 -- date like %H:%M:%S %d-%b-%Y 2012-02-03 00:00:00

To fix this, we can rewrite the Date column using strftime:
Georgia$Date <- strftime(Georgia$Date, "%H:%M:%S %d-%b-%Y")
And now we can read the data without the parse errors.
read_histos(Georgia)
