Time Zones in Planon ProCenter
The following list includes definitions of the concepts and abbreviations used in the MTZ documentation of Planon ProCenter .
For clarification of the UTC time zone, this list includes some examples of other global time zones that are not necessarily used in the body text of this document. For a list of all time zones, refer to the Time zone field.
Time zone
Description
CET
Central European Time. Setting aside the use of daylight saving time during summer, this time zone is used in most countries in the western parts of the European continent. It equals the UTC time + 1 hour (UTC +1).
Database time zone
The time zone applied in the Planon ProCenter database. Note that the database time zone must be identical to the time zone of the database server!
EST
Eastern Standard Time. This time zone is used in eastern parts of the North American continent. It equals the UTC time -5 hours (UTC -5).
GMT
Greenwich Mean Time. Equals UTC. Setting aside the use of daylight saving time during summer, the GMT/UTC time zone is observed in Iceland, Ireland, and the United Kingdom.
Local time
The time in the time zone in which you are physically present.
Multiple time zones (MTZ)
The concept of 'multiple time zones' (MTZ) refers to related activities that take place in different time zones.
Property time zone
The time zone in which a property is physically present.
User time zone
The time zone that has been assigned to the logged on user.
UTC
Universal Time Coordinated, the current international standard. UTC is similar to GMT, except that UTC is more precise, based on atomic time, and takes into account leap seconds. Setting aside the use of daylight saving time during summer, the GMT/UTC time zone is observed in Iceland, Ireland, and the United Kingdom.
ETC/GMTxxx
This time zone is same as the UTC time zone but conforms with the POSIX style signs, which means that the sign will be reversed from the standard ISO 8601 convention. So, in the 'ETC' area, zones west of GMT have a positive sign and zones to the east have a negative sign. For example, 'ETC/GMT-8' is 8 hours ahead of GMT, i.e., GMT+8.
* 
Planon advises you to use the logical time zone convention 'Area/Location' for property and user time zone. Example, America/New_York.

A pick list including the available time zones can be found in time zone fields, for example the Time zone field in Accounts > User groups > Users.

This dialog box can be used to link a time zone to an element: for example a selected user. Time zone fields referring to properties give access to the same pick list, which can be used to link a time zone to the selected property.
After a time zone has been linked to a property or a user, Planon ProCenter will automatically take any related daylight saving time into account.
