Syntax

Envariable: N/A
Element: <TIMEZONES> timezone_acronym:time_offset
timezone_acronym:time_offset
...
</TIMEZONES>
Command-line Option: N/A

TIMEZONES maps timezones to hour offsets from UTC/GMT (Universal Coordinate Time). The TIMEZONES resource can be defined only by the TIMEZONES element The format of each line of content is "timezone_acronym:time_offset", where time_offset is in [-]HHMM notation. Examples of timezone acronyms are: UTC, PDT, EST. The time offsets should be positive for timezones West of UTC, and negative for time zones East of UTC.

NOTE

Timezone settings in MHonArc are the negative inverse of what is used in dates in messages. For example, an EST time will look like the following in a mail message:

    Sat, 10 Sep 1994 15:11:10 -0500

Notice that -0500 is used for EST. However, in MHonArc, EST is mapped to 0500, since 0500 must be added to the specified date/time to get the UTC date/time.

MHonArc has a default list of timezone acronyms defined with time offsets. Therefore, the list given in the resource file will augment the default list. If "Override" attribute is specified, any local lists specified in previous TIMEZONES elements are replaced.

Much of the time, the date used by MHonArc has a time offset instead of a timezone acronym. However, mail messages may contain timezone acronyms in received/sent dates and MHonArc must be told what hour offset to add to the give time to get UTC time to properly sort messages by date.

Examples

Some zone acronyms are not unique, and have different time offsets. The following table describes alternative values for these zones:

Zone	Offset	Description
BST	0300	Brazil Standard
NST	0330	Newfoundland Standard
GST	0300	Greenland Standard

To have the above values used instead of the default values use by MHonArc, the following TIMEZONES setting would be used:

<TimeZones>
BST:0300
NST:0330
GST:0300
</TimeZones>
