blockLocalCivilTime

Converts the clock time to local civil time.

Extends from PartialConvertTime (Converts the simulation time to calendar time in scale of 1 year (365 days), or a multiple of a year).

Information

This component converts the clock time to local civil time. The parameter timZon represents the time zone of the facility (relative to Greenwich Mean Time or the 0th meridian). Time zones west of GMT (e.g. North America) are represented as negative; east of GMT as positive. Fraction of hours are represented in decimals (e.g. for 6:30, use 6.5).

The formula is based on Michael Wetter's thesis (A4.1):

  locTim = greTim + (lon*180/pi)*86400/360 = cloTim - timZon + lon*43200/pi
