- Method Detail
  - buildTimeZone
```
public static SimpleTimeZone buildTimeZone(String ical)
```
    Builds a Java TimeZone from the VTIMEZONE info in an iCal file.
    
    Returns:
    
    a Java TimeZone that matches the iCal one, or NULL if no TZ info present
  - buildTimeZone
```
protected static SimpleTimeZone buildTimeZone(Map<String,String> icalParams)
```
    Internal version that takes the parameters from getICalParams(String) and builds a TimeZone from it. This is not public as it will be refactored when getICalParams(String) is replaced. Note - because it uses the icalParams, we can't handle cases where we're given historic TZ info (eg until 2004 it was that, now it's this)
  - icalLineKeyValue
```
protected static String[] icalLineKeyValue(String icalLine)
```
    Splits an iCal line into key and value by the first unquoted colon.
    
    Parameters:
    
    icalLine - String
  - getICalParams
```
protected static Map<String,String> getICalParams(String icalText)
```
    Turns an iCal event into event + timezone parameters. This is very closely tied to the SPP / VTI implementation, and should be replaced with something more general. Until then, it is deliberately not public.
    
    Parameters:
    
    icalText - iCal text for the event, and the TZ (prefixed)
