Questions:
I have a column of date in this format:
2019-04-17 16:26:17
2019-04-17 16:26:22
2019-04-17 16:26:27
2019-04-17 16:26:32
2019-04-17 16:26:37
2019-04-17 16:26:42
2019-04-17 16:26:47
2019-04-17 16:26:52
2019-04-17 16:26:57
If, for example, the first date is the time t = 0 how can I calculate the time span, in seconds, that elapses at the following dates/times? That data table was automatically generated in .xls file by software during the lab experience. This is an example of the result I would like to achieve
0
5
10
15
20
25
...
125
Can you help me?
Thank you in advance
