man osmium-time-filter (1): 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".
