Non-conventional time units (month as %Y%m.%f" )

Hi,
I'm unable to convert time units using ut_calendar or cd_calendar. The variables (OAFlux: http://oaflux.whoi.edu/data.html) have somewhat unusual time units: (month as %Y%m.%f" ). Does anyone have experience on how to convert the time? The ncdump of the data is included below.
Thanks in advance.

dimensions: lon = 360 ; lat = 180 ; time = UNLIMITED ; // (648 currently)variables: float lon(lon) ; lon:long_name = "longitude" ; lon:units = "degrees" ; lon:standard_name = "longitude" ; lon:axis = "X" ; float lat(lat) ; lat:long_name = "latitude" ; lat:units = "degrees" ; lat:standard_name = "latitude" ; lat:axis = "Y" ; double time(time) ; time:units = "month as %Y%m.%f" ; time:calendar = "proleptic_gregorian" ; short evapr(time, lat, lon) ; evapr:units = "cm/yr" ; evapr:add_offset = 0. ; evapr:scale_factor = 0.1 ; evapr:_FillValue = 32766s ; evapr:comments = "monthly mean evaporation rate" ; short err(time, lat, lon) ; err:units = "cm/yr" ; err:add_offset = 0. ; err:scale_factor = 0.1 ; err:_FillValue = 32766s ; err:comments = "monthly mean estimated error of evaporation rate" ;
