How to use strptime or any other functions to parse millisecond timestamps in R?

 time[1] # [1] "2010-01-15 13:55:23.975" strptime(time[1], format="%Y-%m-%d %H:%M:%S.%f") # [1] NA strptime(time[1], format="%Y-%m-%d %H:%M:%S") # [1] "2010-01-15 13:55:23"`

Provided by ?strptime help file (with an example changed to your value):

  z <- strptime("2010-01-15 13:55:23.975", "%Y-%m-%d %H:%M:%OS") z # prints without fractional seconds op <- options(digits.secs=3) z options(op) #reset options

You can also use strptime(time[1], "%OSn") , where 0 <= n <= 6, without having to set digits.secs .
