Date and Time |
The :gbbopen-tools
module includes useful date and
time parsing and formatting entities.
In addition to UTC offsets, time-of-day entities support the following
time-zone abbreviations for standard-time (non-daylight-savings) offsets:

Time-zone abbreviations used around the world are not unique or universal. The same hour offset can map onto multiple different zone abbreviations, and the same abbreviations are also used to refer to different zones. The above choices of supported abbreviations were made arbitrarily, and the use of UTC offsets is recommended for unambiguous textual representation of the time of day.
