For example, the netCDF file tos_O1_2001-2002.nc used for VTK testing (<a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__midas3.kitware.com_midas_item_206312&d=CwMGaQ&c=uGuXJ43KPkPWEl2imVFDmZQlhQUET7pVRA2PDIOxgqw&r=PPcXhptMPNzBCwHx-o1zqg&m=A7bpyohhfVnNQoUi0GE2BJS2jE2OkxogntGvLqTmVGM&s=HGoAZZDUus7tmDI-abU30H7Ij8Qg_EeQwanbaawq2-w&e=">https://midas3.kitware.com/midas/item/206312</a>)

<p class="MsoNormal"><span style="font-size:10.5pt;color:black">As I recall, the CF convention defines the time dimension using a units property on the variable that specifies some unit of time. One problem that has occurred in the past is that sometimes the
time unit is something that the reader does not recognize as time. What is the time units used in your data set?<o:p></o:p></span></p>
