Thank you for reply, Tytalus

Actually i have researched the fucntion date and it is workable, but my problem in this acticle is converting the date when call the last reboot command.
when I execute the "last reboot > last_reboot.txt" it is plain text. there are no YEAR in the text, so I cannot connvert the plain text without YEAR.

the data in the plain text
reboot system boot Fri Aug 6 15:07
reboot system down Fri Aug 6 15:04
reboot system boot Wed Jul 14 16:12
reboot system down Tue Jul 6 20:04
reboot system boot Tue Jul 6 19:59
reboot system down Fri May 7 10:22
reboot system boot Fri May 7 10:01
wtmp begins Fri May 7 10:01
