Observation: rman saves files according to end date of backup

I noticed the following: An archivelog file backed up at 1.01.2022 23:57:18 will NOT be saved in the folder for 31.01.2022. Instead, it will be saved in the folder for 01.02.2022.
Output from RMAN:

 list archivelog from time '31.01.2022' until time '01.02.2022';
 

Output (excerpt)

450706  1    450701  A 31.01.2022 23:56:46
        Name: /u04/fra/proddb01/archivelog/2022_01_31/o1_mf_1_450701__vwojnvs6_.arc

450707  1    450702  A 31.01.2022 23:57:16
        Name: /u04/fra/proddb01/archivelog/2022_01_31/o1_mf_1_450702__vwokkx0p_.arc

450708  1    450703  A 31.01.2022 23:57:18
        Name: /u04/fra/proddb01/archivelog/2022_02_01/o1_mf_1_450703__vx4cmycs_.arc

The file /u04/fra/proddb01/archivelog/2022_02_01/o1_mf_1_450703__vx4cmycs_.arc has the timestamp Feb 1 00:05
So in this case, the last file generated on 31.01 actually ended up in the folder for files generated on the 01.02
