Bruce,
I don't think so. If you HAVEN'T converted to using SQLite (vs individual files), then maybe you could go look at the file date of the tile in Windows Explorer. It looks like you can right click on a given spot on the picture you have up, and "Open Primary Map Tile Folder" That would tell you at least when you downloaded it. (This doesn't
work if you are using SQLite format to store your tiles.
I HAVE converted to using the SQLite database. So on a whim, I downloaded a tool called DB.Browser (because I was curious) and looked at one of the .sqlitedb files on my hard drive:
C:\SAS.Planet\Sqlite3_Cache\ArcGIS.Hybrid\z16\9\14 \38.56.sqlitedb
See attachment below as to what it looks like. If you have SAS code, you could go look at what the columns mean, and maybe one is a date.
The View menu under Cached Tiles Map implies that there is some date logic associated with the tiles, but I couldn't figure out how it worked just playing with it. And looking at the SAS Wiki, one of the pages says (in bold)
Attention! Mapping services periodically update maps and
satellite images. SAS.Planet cannot automatically track these updates. This mission is assigned to end users. Therefore, claims like “I see a new image in the browser, but SAS.Planet downloads the old one” are not accepted.
Not sure what this means exactly.
You might ask your question on the Sas.Planet forum.
