[R] Diff time returns 2 hours when there is 1

Greetings! I am analysing my data and checking for gaps over 1 hour and
come across the problem that R tells me that there are many 2 hour gaps.
When I go into details, I don't see any of these lapses. Is it something
with the diff() function?

You can see what I am saying, below:

>Time differences in hours
[1] 1 2 1

​Has anyone ever seen something like this? I mean, diff() is one of the
basic functions of R, so it is probable that many people has seen something
similar, before. However, somehow, I can't find an answer string on
stackexchange or analogous pages.​

​Thanks in advance!​
