Issue with time on Linux

[dominicroye]

I have noticed that on Posit Cloud when I import multidimensional geotiff the time is not formatted correctly:

> rast("./data/horas_sol_esp.tiff")
class       : SpatRaster 
dimensions  : 322, 486, 485  (nrow, ncol, nlyr)
resolution  : 0.05, 0.05  (x, y)
extent      : -20, 4.3, 27.65, 43.75  (xmin, xmax, ymin, ymax)
coord. ref. : lon/lat WGS 84 (EPSG:4326) 
source      : horas_sol_esp.tiff 
names       : SDU,   SDU,   SDU,   SDU,   SDU,   SDU, ... 
min values  : NaN,  22.6, 107.3,  57.1,  67.3, 168.5, ... 
max values  : NaN, 247.1, 313.2, 307.6, 341.2, 365.4, ... 
time        : 410227200 to 1682899200 

Usually, on Windows, I would get dates formatted as %Y-%m%d.

I would need to see the file (or at least the auxiliary .json file that terra uses to store time with GTiff) to be able to look into that.

You can fin the used GeoTifff here https://github.com/dominicroye/sun_app/tree/main/data. Thank you
