有人可以帮助我理解为什么使用-mmin'vs -mtime'时我的输出为何不同：
$ ls -l A*
-rw-rw-r-- 1 user1 bin 76755 Feb 5 15:37 A_33292_020519.TXT
-rw-rw-r-- 1 user1 bin 70367 Feb 5 15:37 A_33313_020519.TXT
-rw-rw-r-- 1 user1 bin 74182 Feb 7 13:44 A_51156_020719.TXT
-rw-rw-r-- 1 user1 bin 86991 Feb 7 13:44 A_51164_020719.TXT
$ find . -name A_\* -mtime +1
**< Nothing displayed>**
$ find . -name A_\* -mmin +1440
