If I set HISTTIMEFORMAT var, then 'history' command
prints timestamps. For example:

HISTTIMEFORMAT="%c # "; history

But file ~/.bashrc_history contains no timestamps.
How can it print timestamps if '.bashrc_history' contains no
timestamps ?

It's magic ;)



If you set HISTTIMEFORMAT the first time all entries prior to setting the
variable will get the time stamp of the time the variable was set.

Exit your bash, open a new one and take a look:

tail ~/.bashrc_history.
