Time zone codes

The ISO 8601 standard defines time zone offsets as a numerical value added to a local time to convert it to Coordinated Universal Time (UTC), either as +hh:mm or -hh:mm, or represented by the letter Z to explicitly indicate UTC. For example, +05:30 means 5 hours and 30 minutes ahead of UTC, while -08:00 means 8 hours behind UTC. The offset Z specifically signifies UTC.
