Generate and return the time zone abbreviation corresponding to the current local time or the specified zone
in minutes.

Generate and return the time zone abbreviation corresponding to the current local time or the specified zone
in minutes.
The time zone abbreviation is difficult to infer and generally requires communication with the operating system, which may or may not have it.
The current implementation of this generic interface relies on a predefined internal list of time zone abbreviations to convert the specified zone
in units of minutes to an abbreviation.
Where there are multiple time zone abbreviations available for a single time zone, only a single representative abbreviation is kept in the list.
See the documentation of timeZone_type for the current internal list of zones and abbreviations used by the ParaMonte library.
- Parameters
-
[in] | zone | : The input scalar of type integer of default kind IK, containing the local time zone of the Gregorian calendar in minutes.
(optional, default = getZone()) |
- Returns
abbr
: The output scalar of type integer
of default kind IK containing the local time difference in minutes with respect to the Coordinated Universal Time (UTC).
Possible calling interfaces ⛓
character(:, SK), allocatable :: abbr
integer(IK) :: zone

This module contains classes and procedures for computing, manipulating, and styling dates and times.
- Warning
- When the input argument
zone
is out of the supported range ( \(-12\times60\) minutes UTC and \(+14\times60\) minutes UTC), the output string will be empty.
-
This generic interface does not currently take into account the daylight savings calendar.
This can lead to shifts in the output zones by up to one hour.

- Test:

- Todo:
- High Priority: Currently, the zone abbreviation is derived from a predefined list.
The zone abbreviation must be inferred directly from the operating system.
On Windows, this could be also be done via the Powershell command (Get-Date).IsDaylightSavingTime()
to test whether the daylight savings is activated.
On Unix, The command date +"\%Z"
outputs the zone abbreviation.
