NAME

       gtimer - an application for recording time spent on user-defined tasks.

SYNOPSIS

       gtimer [-midnight offset] [-weekstart day] [-nosplash] [-resume] [-start task]

DESCRIPTION

       GTimer allows the user to time one or more activities.  Users define tasks that can be timed.  Text annotations can also be added to tasks.
       Reports can be generated that summarize time spent and annotations.

OPTIONS

       -midnight offset
	       Specify the offset of midnight to use.  Users can allow time spent after midnight to be recorded for the previous day.	For  exam-
	       ple, the command

	       gtimer -midnight 400

	       will not consider everything 3:59AM the previous day.

       -weekstart day
	       Specify	which  day  of	the  week  should be considered the beginning of the week when generating reports.  day should be a number
	       between 0 and 6, where 0 is Sunday.  For example, the command

	       gtimer -weekstart 1

	       will use Monday as the first day of the week for all weekly reports.  The default is 0 (Sunday).

       -resume Start timing any tasks that were still be timed when GTimer last exited.

       -start taskname
	       Start timing the specified task immediately.  This option can be used more than once on the command line.   For	example,  you  can
	       start a tasks with:

	       gtimer -start 'GTimer development'

       -nosplash
	       Do not display the splash window on startup.
