I have a dataset Peil_1 with column "timestamp" representing the time "value" was measured.
# A tibble: 175,350 x 5
Timestamp Value `Quality Code` `Absolute Value` `AV Quality Code`

I want to convert Peil_1$timestamp to a time or date format. I thought to use as.date, but I don't know how to handle the T00: 00: 00,000 + 1: 00 part
