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

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

Regarding this link you can make the first solution provided by krzyk permanent by executing   echo  export HISTTIMEFORMAT   d  m  y  T     gt  gt     bash profile source    bash profile

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

Try this    gt  HISTTIMEFORMAT   d  m  y  T     gt  history   You can adjust the format to your liking  of course
