getvardims show missing dimension; but in fact, there is one dimension with printVarSummary

Hello,

    The command getvardims(time) showed missing dimension. But in fact,
there is one dimension with printVarSummary (time) as follows. I wonder
why this is possible?

#####
print("time")
print(typeof(time))
print(getvardims(time))
printVarSummary(time)

#####
(0) time
(0) float
(0) missing

Variable: time
Type: float
Total Size: 11680 bytes
            2920 values
Number of Dimensions: 1
Dimensions and sizes: [2920]
Coordinates:

    Many thanks,

                           Yi-Chih
