This section specifies general <<acronym_hl7>> V2 requirements and mappings, which apply to the <<vol2_clause_appendix_sdpi_dec_gateway>> as well as to the <<vol2_clause_appendix_sdpi_acm_gateway>> sections below.

==== Time Zone Setting
For the <<acronym_hl7>> V2 data reporting, it is impportant that the time zone is set correctly at the <<term_point_of_care_device>>.
Timestamps can be specified in HL7 v2 in both UTC and local time.

.R8120
[sdpi_requirement#r8120,sdpi_req_level=shall,sdpi_max_occurrence=1]
****
A <<actor_somds_dec_gateway>> / <<actor_somds_acm_gateway>> shall only export data from <<acronym_mds>> entities, which have a valid timezone defined in the *pm:ClockState/@TimeZone* attribute.

.Notes
[%collapsible]
====
NOTE: In <<ref_hl7_v2>>, all timestamps are defined as local time and the time zone is optional. Therefore, a <<actor_somds_dec_gateway>> / <<actor_somds_acm_gateway>> is required to convert the UTC time provided by the <<actor_somds_provider>> into local time.
NOTE: As stated in <<ref_ihe_pcd_tf_2_2019>> all observation times reported SHOULD be UTC, as indicated by including a time zone offset of +0000.

NOTE: If the timestamps are to be specified in local time, it is important that the time zone is set correctly at the <<term_point_of_care_device>>.

NOTE: It is not always guaranteed that the timezone configured at the <<actor_somds_provider>> and/or <<actor_somds_dec_gateway>> / <<actor_somds_acm_gateway>> corresponds with the timezone of the <<acronym_mds>> entities, for example, when a <<actor_somds_provider>> acting as device aggregator and/or the <<actor_somds_dec_gateway>> / <<actor_somds_acm_gateway>> are running in a data center located in a different timezone than the <<acronym_mds>> entities.
