- The <productname>PostgreSQL</productname> Global Development Team provides
- the <productname>Postgres</productname> software code tree as a public service,
- without warranty and without liability for it's behavior or performance.
- However, at the time of writing:

- <para>
- The author of this statement, a volunteer on the <productname>Postgres</productname>
- support team since November, 1996, is not aware of
- any problems in the <productname>Postgres</productname> code base related
- to time transitions around Jan 1, 2000 (Y2K).
- </para>

- <para>
- The author of this statement is not aware of any reports of Y2K problems
- uncovered in regression testing
- or in other field use of recent or current versions
- of <productname>Postgres</productname>. We might have expected
- to hear about problems if they existed, given the installed base and
- the active participation of users on the support mailing lists.

- To the best of the author's knowledge, the
- assumptions Postgres makes about dates specified with a two-digit year
- are documented in the current
- <ulink url="http://www.postgresql.org/docs/user/datatype.htm">User's Guide</ulink>
- in the chapter on data types.
- For two-digit years, the significant transition year is 1970, not 2000;
- e.g. <quote>70-01-01</quote> is interpreted as <quote>1970-01-01</quote>,
- whereas <quote>69-01-01</quote> is interpreted as <quote>2069-01-01</quote>.

- Any Y2K problems in the underlying OS related to obtaining "the
- current time" may propagate into apparent Y2K problems in

- for further discussion of Y2K issues, particularly
- as it relates to open source, no fee software.
