HISTTIMEFORMAT   d  m  y  H  M     For any commands typed prior to this  it will not help since they will just get a default time of when you turned history on  but it will log the time of any further commands after this   If you want it to log history for permanent  you should put the following  line in your    bashrc  export HISTTIMEFORMAT   d  m  y  H  M

It depends on the shell  and its configuration  in standard bash only the command is stored without the date and time  check  bash history if there is any timestamp there    To have bash store the timestamp you need to set HISTTIMEFORMAT before executing the commands  e g  in  bashrc or  bash profile  This will cause bash to store the timestamps in  bash history  see the entries starting with

In case you are using zsh you can use for example the -E or -i switch  history -E  If you do a man zshoptions or man zshbuiltins you can find out more information about these switches as well as other info related to history  Also when listing   -d     prints timestamps for each event  -f     prints full time-date stamps in the US  MM DD YY hh mm  format  -E     prints full time-date stamps in the European  dd mm yyyy hh mm  format  -i     prints full time-date stamps in ISO8601  yyyy-mm-dd hh mm  format  -t fmt prints time and date stamps in the given format  fmt is formatted with the strftime function with the zsh extensions  described  for  the   D string  prompt format in the section EXPANSION OF PROMPT SEQUENCES in zshmisc 1    The resulting formatted string must be no more than 256 characters or will not be printed  -D     prints elapsed times  may be combined with one of the options above
