What is UTC? What is Z or Zulu time?

Weatheroffice Frequently Asked Questions - Environment Canad...
UTC is the international abbreviation for Coordinated Universal Time. It is the local time at the Greenwich meridian (0°). The World Meteorological Organization (WMO) has adopted the UTC as the standard time for use in reporting of all meteorological data. Times in UTC sometimes get the suffix Z, i.e. 16Z. From the Z suffix came the mnemonic "Zulu" (as used in international marine communications standards).

When transforming an hCalendar to a .ics file, do I have to convert the time to UTC?
