Simon Michael ae5a9439d0 count time elapsed in open timelog entries, ignore time zone
Any open sessions in a timelog will be considered clocked out as of the
current time, and included in calculations. Also, contrary to the earlier
patch we now ignore timezone everywhere and deal only with local times.
This might need revisiting eg to track time while crossing timezones.

hledger - a ledger-compatible text-based accounting tool.
Copyright (c) 2007-2009 Simon Michael <simon@joyful.com>
Released under GPL version 3 or later.
hledger is a haskell clone of John Wiegley's "ledger" text-based
accounting tool (http://newartisans.com/software/ledger.html).
It generates ledger-compatible register & balance reports from a plain
text ledger file, and demonstrates a functional implementation of ledger.
For more information, see hledger's home page: http://joyful.com/hledger
You can use the command line:
> $ hledger --help
or ghci:
> $ ghci hledger
> > l <- ledgerfromfilewithopts [] [] "sample.ledger"
> > balance [] [] l
> $-1 assets
> $2 expenses
> $-2 income
> $1 liabilities
> > register [] ["income","expenses"] l
> 2008/01/01 income income:salary $-1 $-1
> 2008/06/01 gift income:gifts $-1 $-2
> 2008/06/03 eat & shop expenses:food $1 $-1
> expenses:supplies $1 0
