_______________________________________________________
In general CDS Invenio uses date/timestamps specified in the local timezone
(for eg. for records creation/modification times stored in the DB) without
any special consideration of the Daylight Saving Time offset: this can lead
to ambiguous local times, as the same datestamps (during winter DST switch)
can occur twice a year.
To avoid any confusion (especially with timezone conversions and any
synchronization process relying on dates) one could check the feasibility (or
simply the need) of using Coordinated Universal Time (UTC) as default timezone
for all date/timestamps.
Note that this task would also include checking the behavior of MySQL
regarding date and timezones:
