Need an Correct SQL Query to get updated start time and stop time from OTL Submitted time entries

Below is the reference query which is pulling duplicates becuase of confusion between range and measures types.

SELECT

	papf.person_number,

	htc.start_time,

	htc.stop_time

	FROM

	per_all_people_f papf,

	hwm_tm_rec            htc,

	hwm_tm_rec_grp_usages htrgu,

	hwm_tm_rec_grp        htrg,

	hwm_grp_type          hgt

	WHERE

	htc.resource_type = 'PERSON'

	AND htc.latest_version = 'Y'

	AND htc.layer_code = 'TIME_RPTD'

	AND htc.tm_rec_id = htrgu.tm_rec_id

	AND htc.tm_rec_version = htrgu.tm_rec_version

	AND htrgu.latest_version = 'Y'

	AND htrgu.tm_rec_grp_id = htrg.tm_rec_grp_id
