   and perhaps the extras in [ledgerutils.el](http://hub.darcs.net/simon/ledgertools/ledgerutils.el)
 
 - at the command line, use these bash aliases:

     ```cli
     alias ti='echo i `date "+%Y-%m-%d %H:%M:%S"` $* >>$TIMELOG'
     alias to='echo o `date "+%Y-%m-%d %H:%M:%S"` >>$TIMELOG'
     ```

 - or use the old `ti` and `to` scripts in the [ledger 2.x repository](https://github.com/ledger/ledger/tree/maint/scripts).
   These rely on a "timeclock" executable which I think is just the ledger 2 executable renamed.
