# aren't parsed in any way, so that field could be used for nearly

# Start and end times should be in 24-hour format, for example 13:00.
# If you work after midnight, don't wrap the time around zero -- report
# it as 24:00 or 25:00. This timesheet is uninsightful about time
# subtraction and will ignore lines that appear to be negative.

# Times are also indexed by title when you produce a CSV file. This can
# be useful for analysis.

# For example:
2010.1210       09:00   12:00   Working on X    Added feature X1
2010.1211       13:00   17:00   Working on X    Added feature X2
