NAMEr.timestamp - Modifies a timestamp for a raster map.Print/add/remove a timestamp for a raster map. KEYWORDSraster, metadata, timestamp, timeSYNOPSISr.timestampr.timestamp --help r.timestamp map=name [date=timestamp] [--help] [--verbose] [--quiet] [--ui] Flags:
Parameters:
DESCRIPTIONThis command has 2 modes of operation. If no date argument is supplied, then the current timestamp for the raster map is printed. If a date argument is specified, then the timestamp for the raster map is set to the specified date(s). See examples below.NOTESStrings containing spaces should be quoted. For specifying a range of time, the two timestamps should be separated by a forward slash. To remove the timestamp from a raster map, use date=none.TIMESTAMP FORMATThe timestamp values must use the format as described in the GRASS Datetime Library. The source tree for this library should have a description of the format. For convenience, the formats are reproduced here:There are two types of datetime values:
AbsoluteThe general format for absolute values is:day month year [bc] hour:minute:seconds timezone day is 1-31 month is jan,feb,...,dec year is 4 digit year [bc] if present, indicates dates is BC hour is 0-23 (24 hour clock) minute is 0-59 second is 0-59.9999 (fractions of second allowed) timezone is +hhmm or -hhmm (eg, -0600)Some parts can be missing, for example 1994 [bc] Jan 1994 [bc] 15 jan 1000 [bc] 15 jan 1994 [bc] 10 [+0000] 15 jan 1994 [bc] 10:00 [+0100] 15 jan 1994 [bc] 10:00:23.34 [-0500] RelativeThere are two types of relative datetime values, year-month and day-second. The formats are:[-] # years # months [-] # days # hours # minutes # secondsThe words years, months, days, hours, minutes, seconds are literal words, and the # are the numeric values. Examples: 2 years 5 months 2 years 5 months 100 days 15 hours 25 minutes 35.34 seconds 100 days 25 minutes 1000 hours 35.34 secondsThe following are illegal because it mixes year-month and day-second (because the number of days in a month or in a year vary): 3 months 15 days 3 years 10 days EXAMPLESPrints the timestamp for the "soils" raster map. If there is no timestamp for "soils", nothing is printed. If there is a timestamp, one or two time strings are printed, depending on if the timestamp for the map consists of a single date or two dates (ie start and end dates).r.timestamp map=soilsSets the timestamp for "soils" to the single date "15 sep 1987". r.timestamp map=soils date=’15 sep 1987’Sets the timestamp for "soils" to have the start date "15 sep 1987" and the end date "20 feb 1988". r.timestamp map=soils date=’15 sep 1987/20 feb 1988’Sets the timestamp for "soils" to have the start date "18 feb 2005 10:30:00" and the end date "20 jul 2007 20:30:00". r.timestamp map=soils date=’18 feb 2005 10:30:00/20 jul 2007 20:30:00’Removes the timestamp for the "soils" raster map. r.timestamp map=soils date=none KNOWN ISSUESSpaces in the timestamp value are required.SEE ALSOr.info, r3.timestamp, v.timestampAUTHORMichael Shapiro, U.S.Army Construction Engineering Research LaboratorySOURCE CODEAvailable at: r.timestamp source code (history)Main index | Raster index | Topics index | Keywords index | Graphical index | Full index © 2003-2021 GRASS Development Team, GRASS GIS 7.8.6 Reference Manual
