Under JAR it is pretty simple. You may log IMC time at your leasure, but nobody is really interested as that is not a requirement under JAR. It has to be logged in the remarks column (JAR FCL 1.080 (b) (4) (v)).
You have to log operational conditions, one of them is flying under IFR rules (JAR FCL 1.080 (b) (5)). That is a requirement and has to be done. For those of us flying IFR only that means that IFR time is the same as total time. For others that fly mixed operations that may differ.
PICUS may be logged if the method of supervision is acceptable to the authority (JAR FCL 1.080 (c) (5)), it has to be countersigned by the pilot in command (JAR FCL 1.080 (c) (1) (v)). This is a statement that is open to debate. The uk has guidelines in its LASORS that allow every line captain to supervise a PICUS flight, in many other european countries that is not possible and PICUS can only be flown in an especially approved program, usually during the upgrading process.
