[General] annotate time YYYY MM DD

My_name_is_nobody · August 20, 2015, 03:36

Hello,
I work on Netcdf files and in it i have a time dimension that is written as below :

time:units = "months since 1993-12-01 00:00:00" ;
time:time_origin = "1993-12-01 00:00:00" ;
time:standard_name = "Time axis" ;
time:axis = "t" ;
time:calendar = "gregorian" ;
time:long_name = "time" ;

The problem is that on paraview i m not able to display the date in the format YYYY-MM-DD even if i can display the Time (in Days or Hours) with the Source -> Annotate Time or with the Filter -> annotate Time.
I tried to write the date in my netcdf files but i can't find this variable in Paraview. I know it's possible because i saw some animation with the real date but i don't know how.

Thank you in advance for your assistance.

Quick question: Can you provide a small example file?

My_name_is_nobody · August 24, 2015, 03:01

I can give you the complete header of my files but the files themselves are very large (between 500Mo and 20Go). I hope it's enough for you.

dimensions:
time = UNLIMITED ; // (8760 currently)
cell = 181724 ;
nvert = 4 ;
variables:
double lat(cell) ;
lat:long_name = "latitude" ;
lat:bounds = "bounds_lat" ;
lat:units = "degrees_north" ;
double lon(cell) ;
lon:long_name = "longitude" ;
lon:bounds = "bounds_lon" ;
lon:units = "degrees_east" ;
int time(time) ;
time:units = "months since 1994-01-01 00:00:00" ;
time:time_origin = "1994-01-01 00:00:00" ;
time:standard_name = "Time axis" ;
time:axis = "t" ;
time:calendar = "gregorian" ;
time:long_name = "time" ;
float tas(time, cell) ;
tas:long_name = "Air temperature at 2m" ;
tas:coordinates = "lon lat" ;
tas:_FillValue = 9.96921e+36f ;
double bounds_lon(cell, nvert) ;
bounds_lon:_FillValue = 9.96920996838687e+36 ;
double bounds_lat(cell, nvert) ;
bounds_lat:local_name = "cornerslat" ;

Thank you for your reply.

Greetings My_name_is_nobody,

Sorry, but I need a fully working file, which was why I asked for a small one

The reason why I need one is to diagnose how the time data is being loaded by ParaView. Because as far as I know, ParaView usually only works with time in seconds, therefore I don't have a working example that has a complete date which would be rendered in the way you're asking for.
In addition, I don't know if those time entries are being loaded as "Fields" from the file or if they are simply ignored.

Best regards,
Bruno
