How can I add timestamp in osmdata_sf() results?

Question

When I query osm data, I want to receive the timestamp, when some object was added or changed, is it possible to include this data? There is my query:

q <- opq("London",timeout = 20000) %>%
  add_osm_feature(key = "landuse", value="grass",value_exact = F) %>%
  osmdata_sf()

Then I use q$osm_polygons data.

in general, I want to convert this script to R:

[out:json][timeout:200];
{{geocodeArea:London}}->.searchArea;
way["landuse"~"grass"](area.searchArea);
(._;>;);
out meta;

I received the great solution from the contributor of the osm_data package on github. There is the link from github - https://github.com/ropensci/osmdata/issues/269#issuecomment-1073748224 — vanhry, Mar 22 '22 at 15:05
Hi vanhry, thank you for sharing the mpadge's code which is indeed very useful. Is this code sufficient for your needs or do you still want a way to add timestamps to each polygon of your `sf` object? — lovalery, Mar 25 '22 at 12:57

Please feel free to ignore this answer if it doesn't fit your question, as I am not sure this is exactly what you are looking for.

When you query with osmdata you get a list with several elements. One of them is the timestamp, but I think is the timestamp of the query, nothing else:

library(osmdata)
#> Data (c) OpenStreetMap contributors, ODbL 1.0. https://www.openstreetmap.org/copyright

q <- opq("London",timeout = 20000) %>%
  add_osm_feature(key = "landuse", 
                  value="grass",value_exact = F) %>%
  osmdata_sf()

timestamp <- q$meta$timestamp

timestamp
#> [1] "[ lu\\. 2 mar 2022 17:01:08 ]"

# Use in polygons
pols <- q$osm_polygons
pols$timestamp <- timestamp
