           8             : ! !DESCRIPTION: Module hco\_timeshift\_mod.F90 contains routines to shift the
           9             : ! file reference time by a given value. Time stamps shifts can be provided as
          10             : ! optional fifth element to the time stamp attribute in the HEMCO configuration
          11             : ! file.

          14             : ! For instance, consider the case where 3-hourly averages are provided in
          15             : ! individual files with centered time stamps, e.g.: file.yyyymmdd\_0130z.nc,
          16             : ! file.yyyymmdd\_0430z.nc, ..., file.yyymmdd\_2230z.nc
          17             : ! To read these files *at the beginning* of their time intervals, the time
          18             : ! stamp can be shifted by 90 minutes, e.g. the file name, variable, and time
          19             : ! attribute section reads:
          20             : ! ... file.\$yyyy$mm$dd\_\$hh\$mnz.nc VARNAME 2000-2016/1-12/1-31/0-23/+90minutes ...

          23             : ! At time 00z, HEMCO will then read file 0130z and keep using this file until
          24             : ! 03z, when it switches to file 0430z. Similarly, it is possible to shift the
          25             : ! file reference time by any number of years, months, days, or hours. Time
          26             : ! shifts can be forward or backward in time (use - sign to shift backwards).
