Are they calculated in seconds like the cpuTime?

Yes, the execution statistics view shows these in seconds. The Agent
Controller (which does the data collection) uses a more granular time stamp
on the method entry and exit events.

How can I see the granularity used on Linux about these events(and others
if possible)?

The precision is in nanoseconds for these attributes, the granularity might
be nanosecond, although that depends on the machine speed, if is too slow it
might be more coarse then nanosecond.

Their values come from the "time" attribute of methodEntry and methodExit
events (look at a raw trace, a trcxml file).

Here is the raw profiling trace specification (events spec):
