timestamp, date formatting,csv-file

[Faruk]

Hey Community,
Due to problems regarding xes file import, I converted the xes file into a csv file, for this I had to redefine the time stamp attribute of the type date into a string, this time stamp is now in the string format of an xes file, if you have a Idea how I change this date format so that I can also use these timestamps in my event logs for Process Mining?

the timestamp format seems like that:

2021-03-23T15:36:21.558+0100

Thank you for your Help

string <- "2021-03-23T15:36:21.558+0100"
ymd_hms(string)
#> [1] "2021-03-23 14:36:21 UTC"

great, now I have to make this change for the whole csv file ... do you know how it is possible to change all timestamp attributes so that they got this format?

edit the csv file to insert a new field name
