object

csdf object to get summary for

a list summarizing stored data with summary.csdf class assigned to trigger print.summary.csdf S3 method.

List components are:

granularity: difftime for smallest positive non-zero interval between measurements.
ts.ok: TRUE if TIMESTAMP column in @data slot is monotonic. If FALSE, potentially unintentional clock correction might have taken place, or other serious data problem.
rn.ok: TRUE if RECORD is sequential in slot data of csdf object. CR program reload results in RECORD counter reset. If TOA5 file contains restarts it may indicate that parts of a file were produced with a different CR Basic program.

`nogap`	`TRUE` if adjacent records are granularity apart. You might have issues if `FALSE`.
`gaps`	a `vector containing TIMESTAMP befor gaps.`
`from`	initial/minimal TIMESTAMP
`to`	final/maximal TIMESTAMP
