How to covert string value to datetime

Question

I have a csv file where the date is stored in mm/dd/yyyy format 8/18/2015 12:23:57 PM. When I import this file, it gets imported in string format.

How to convert this to datetime value after importing? I tried to convert while importing, but all the values were as NA.

We can do this with POSIXct

as.POSIXct(str1, format = "%m/%d/%Y %I:%M:%S %p")

str1 <- "8/18/2015 12:23:57 PM"

@maankumar Try `dt$myCleanDate – zx8754 Jul 06 '17 at 11:12
After doing this all the values became N/A. Any idea what went wrong. – Kumar Jul 06 '17 at 11:48
@Kumar The code is based on the format you showed and zx8754's code should work if your format is the same – akrun Jul 06 '17 at 11:53
