sudo date nnddhhmmyyyy.ss


Description for Command
  • nn is a two digit month, between 01 to 12.
  • dd is a two digit day, between 01 and 31, with the regular rules for days according to month and year applying.
  • hh is two digit hour, using the 24-hour period so it is between 00 and 23.
  • mm is two digit minute, between 00 and 59.
  • yyyy is the year; it can be two digit or four digit: your choice. I prefer to use four digit years whenever I can for better clarity and less confusion.
