Data import [closed]

I am trying to import a table with datetime values in r, and the values are not imported. The column with the values appears with NA and the following error is reported.

Parsed with column specification:
    cols(
    HTV = col_time(format = "")
    )
Warning: 15 parsing failures.
row col   expected   actual
   1 HTV valid date 46:57:00
   2 HTV valid date 42:12:00
   3 HTV valid date 67:25:00
   4 HTV valid date 62:53:00
   5 HTV valid date 27:50:00
