I deliberately chose not to include all of the citation because JAR-FCL1.080 is not law and never has been. The logging requirements in the UK are confined to those listed in Art 79 which are similar but different.
The JAA have offered a definition of Instrument Flight Time (IFT) within 1.080, but then use undefined phrases such as IFC to qualify IFT. Elsewhere, they base certain qualifications on hours in accordance with IFR, something nobody logs and hence the reason for the original question. One can only conclude that the authors had no fundamental understanding of the IFR, and assumed that IFR-IFT and IFC (IMC) are inextricably linked. The concept of IFR in VMC is alien to them.
