DESCRIPTION

       t.info  reports  information  about  any  dataset  that  is  registered in the temporal database in human
       readable or shell script style. Datasets are  raster,  3D  raster  and  vector  maps  as  well  as  their
       corresponding space time datasets (STRDS, STR3DS and STVDS). This module reports the information that are
       stored in the temporal database. These are basic information (id, name, mapset, creator,  creation  time,
       temporal  type),  the  temporal  and  spatial  extent and dataset type specific metadata. The user has to
       utilize r.info, r3.info, v.info to report detailed information about raster, 3D raster and  vector  maps,
       since not all map specific information and metadata are stored in the temporal database.

       In addition, information about the chosen temporal database backend can be reported.

NOTES

       Temporal  databases  stored in other mapsets can be used as long as they are in the user’s current mapset
       search path (managed with g.mapsets).

       The "granularity" is the smallest gap size between the found time instances, i.e.  it the greatest common
       divisor between all gaps in the time series.
