Exporting time prints from Kinovea and chaning the time to R format

[jlahti]

Hey guys!
Question concerning changing a time format to R friendly (as.POSIXct). When exporting kinematic time points from Kinovea into an XML spreadsheet, time column data is printed out in the following format: 0:00:02:886 (693). If I have understood this correctly as a beginner in R, I have to first be able to write a code that isolates away "(693)" from the code, then adding also the current date, because isnt as.POSIXct format specifically as example: ("1971-05-14 11:25:15")?
This would get even more complex by adding current date first, so a bit out of my league here.
Friendly regards
Johan

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue or at least some sample data of your input and desired output on a copy/paste friendly format? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
