+.SH DESCRIPTION
+.B __pmParseTime
+is designed to encapsulate the interpretation of a time point specification in
+command line switches for use by the PCP client tools.
+.P
+This function expects to be called with the time point specification as
+.BR string .
+If the tool is running against PCP archive(s), you also
+need to supply the start time of the first (only) archive as
+.BR logStart ,
+and the end of the last (only) archive as
+.BR logEnd .
+See
+.BR pmGetArchiveLabel (3)
+and
+.BR pmGetArchiveEnd (3)
+for how to obtain values for these parameters.
+If the tool is running against a live feed of performance data,
+.B logStart
+should be the current time (but could be aligned on the next second
+for example), while
+.B logEnd
+should have its tv_sec component set to INT_MAX.
+.P
+The
+.B rslt
+structure must be allocated before calling
+.BR __pmParseTime .
+.P
+You also need to set the current PCP reporting time zone to correctly
+reflect the \-z and \-Z command line parameters before calling
+.BR __pmParseTime .
+See
+.BR pmUseZone (3)
+and friends for information on how this is done.
+.P
+If the conversion is successful,
+.B __pmParseTime
+returns 0, and fills in
+.B rslt
+with the time value defined by the input
+parameters. If the argument strings could not be parsed, it returns \-1
+and a dynamically allocated error message string in
+.BR errMsg .
+Be sure to
+.BR free (3C)
+this error message string.
