I am writing to formally request a change in the naming of the time zone for Viet Nam in your database. Currently, the time zone is listed as "Asia/Ho_Chi_Minh." However, I would like to propose that this be updated to "Asia/Ha_Noi" to reflect the official and more widely recognized name of the time zone.
There is already a timezone identifier "Asia/Hanoi" but it is defined in the "backzone" file because it has been the same time as "Asia/Ho_Chi_Minh" since 1970. It may or may not be installed on various operating systems.
Hà Nội, as the capital city of Viet Nam, is the administrative and political center of the country. It holds significant historical, cultural, and socio-economic importance. Consequently, using Hà Nội as the reference point for the country's time zone would be more appropriate and align with international standards and practices.
The timezone identifier string for a region is based on the most populous city in the region, not on political centers. For example, the TZ database contains "Asia/Shanghai" (rather than the capital city "Asia/Beijing") for this reason.
