NAME

       osmium-time-filter - filter OSM data by time from a history file

SYNOPSIS

       osmium time-filter [OPTIONS] OSM-HISTORY-FILE [TIME]
       osmium time-filter [OPTIONS] OSM-HISTORY-FILE FROM-TIME TO-TIME

DESCRIPTION

       Copy all objects that were valid at the given TIME or in the time period between FROM-TIME
       (inclusive) and TO-TIME (not inclusive) from the input file into the output file.   If  no
       time is given, the current time is used.

       Usually  the  INPUT-FILE will be an OSM data file with history.  If both FROM-TIME and TO-
       TIME are given, the result will also have history  data,  it  will  also  include  deleted
       versions of objects.

       If  only  a  single  point in time was given, the result will be a normal OSM file without
       history containing no deleted objects.

       The format for the timestamps is “yyyy-mm-ddThh:mm:ssZ”.

       This commands reads its input file only once and writes its output file in one  go  so  it
       can be streamed, ie.  it can read from STDIN and write to STDOUT.

COMMON OPTIONS

       -h, --help
              Show usage help.

       -v, --verbose
              Set  verbose  mode.   The program will output information about what it is doing to
              STDERR.

       --progress
              Show progress bar.  Usually a progress bar is only displayed if STDOUT  and  STDERR
              are  detected  to  be  TTY.  With this option a progress bar is always shown.  Note
              that a progress bar will never be shown when reading from STDIN or a pipe.

       --no-progress
              Do not show progress bar.  Usually a progress bar is displayed if STDOUT and STDERR
              are  detected  to be a TTY.  With this option the progress bar is suppressed.  Note
              that a progress bar will never be shown when reading from STDIN or a pipe.

INPUT OPTIONS

       -F, --input-format=FORMAT
              The format of the input file(s).  Can be used to set the input format if  it  can’t
              be  autodetected  from  the  file  name(s).  This will set the format for all input
              files, there is no way to set the format for some input files  only.   See  osmium-
              file-formats(5) or the libosmium manual for details.

OUTPUT OPTIONS

       -f, --output-format=FORMAT
              The  format  of  the  output file.  Can be used to set the output file format if it
              can’t be autodetected from the output file name.  See osmium-file-formats(5) or the
              libosmium manual for details.

       --fsync
              Call fsync after writing the output file to force flushing buffers to disk.

       --generator=NAME
              The  name  and version of the program generating the output file.  It will be added
              to the header of the output file.  Default is “osmium/” and the version of osmium.

       -o, --output=FILE
              Name of the output file.  Default is `-' (STDOUT).

       -O, --overwrite
              Allow an existing output file to be overwritten.  Normally osmium  will  refuse  to
              write over an existing file.

       --output-header=OPTION=VALUE
              Add  output header option.  This command line option can be used multiple times for
              different OPTIONs.  See  the  osmium-output-headers(5)  man  page  for  a  list  of
              available  header  options.   For  some  commands  you  can  use the special format
              “OPTION!” (ie.  an exclamation mark after the OPTION and no value set) to  set  the
              value to the same as in the input file.

DIAGNOSTICS

       osmium time-filter exits with exit code

       0      if everything went alright,

       1      if there was an error processing the data, or

       2      if there was a problem with the command line arguments.

MEMORY USAGE

       osmium time-filter does all its work on the fly and doesn’t keep much data in main memory.

EXAMPLES

       Extract current planet file from history planet:

              osmium time-filter -o planet.osm.pbf history-planet.osh.pbf

       Extract planet data how it appeared on January 1 2008 from history planet:

              osmium time-filter -o planet-20080101.osm.pbf history-planet.osh.pbf 2008-01-01T00:00:00Z
