Date/Time Conversion

Hi,

i have a netcdf file with a date/time field

Variable: time (coordinate)
Type: double
Total Size: 328 bytes
            41 values
Number of Dimensions: 1
Dimensions and sizes: [time | 41]
Coordinates:
Number Of Attributes: 3
  standard_name : time
  units : day as %Y%m%d.%f
  calendar : proleptic_gregorian
(0) 19601231.99930555
(1) 19611231.99930555
(2) 19621231.99930555

and .99930555 means 23:59:00

I want to convert this only into years.
How can i extract the year (maybe with substring or with date conversion functions)?

Cheers,
Ronny
