A reader for the timeclock file format generated by timeclock.el
|
|
(<http://www.emacswiki.org/emacs/TimeClock>). Example:
|
|
|
|
@
|
|
i 2007\/03\/10 12:26:00 hledger
|
|
o 2007\/03\/10 17:26:02

From timeclock.el 2.6:
|
|
|
|
@
|
|
A timeclock contains data in the form of a single entry per line.
|
|
Each entry has the form:
|
|
|
|
CODE YYYY/MM/DD HH:MM:SS [COMMENT]
|
|
|
|
CODE is one of: b, h, i, o or O. COMMENT is optional when the code is
|
|
i, o or O. The meanings of the codes are:
|
|
|
|
b Set the current time balance, or \"time debt\". Useful when
|
|
archiving old log data, when a debt must be carried forward.
|
|
The COMMENT here is the number of seconds of debt.
|
|
|
|
h Set the required working time for the given day. This must
|
|
be the first entry for that day. The COMMENT in this case is
|
|
the number of hours in this workday. Floating point amounts
|
|
are allowed.
|
|
|
|
i Clock in. The COMMENT in this case should be the name of the
|
|
project worked on.
|
|
|
|
o Clock out. COMMENT is unnecessary, but can be used to provide
|
|
a description of how the period went, for example.
|
|
|
|
O Final clock out. Whatever project was being worked on, it is
|
|
now finished. Useful for creating summary reports.
