Tiles can get marked as dirty twice

https://github.com/openstreetmap/mod_tile/blob/master/src/store_file.c#L281

has

if (touchCalendar.tm_year > 105) { // Tile hasn't already been marked as expired

the logic here was that when tiles are marked dirty, their mod time was set back 20 years. "tm_year" is years since 1900, so this works find until 2025 (20 years before 2024 is before 2005). However, it is now 2026. Tiles can get set "dirty" twice:

ls -alt /var/cache/renderd/tiles/ajt/18/0/0/17/244/200/252/128.meta
-rw-r--r-- 1 _renderd _renderd 373630 Mar 14 1986 /var/cache/renderd/tiles/ajt/18/0/0/17/244/200/252/128.meta

A "cludge" might just nudge 105 up a bit; a better fix would calculate the replacement for "105" based on the current wall clock date.

Good find, I will take a look at the logic and see what the fix could be. Thanks!
