getTimestamp
public long getTimestamp()Returns the corresponding timestamp (seconds since Epoch). Example:
TimeParser p = new TimeParser("now-1day"); TimeSpec ts = p.parse(); System.out.println("Timestamp was: " + ts.getTimestamp();
- Returns:
- Timestamp (in seconds, no milliseconds)
-
dump
String dump() -
getTimes
Use this static method to resolve relative time references and obtain the corresponding Calendar objects. Example:
TimeParser pStart = new TimeParser("now-1month"); // starting time TimeParser pEnd = new TimeParser("start+1week"); // ending time TimeSpec specStart = pStart.parse(); TimeSpec specEnd = pEnd.parse(); GregorianCalendar[] gc = TimeSpec.getTimes(specStart, specEnd);
- Parameters:
spec1
- Starting time specificationspec2
- Ending time specification- Returns:
- Two element array containing Calendar objects
-
getTimestamps
Use this static method to resolve relative time references and obtain the corresponding timestamps (seconds since epoch). Example:
TimeParser pStart = new TimeParser("now-1month"); // starting time TimeParser pEnd = new TimeParser("start+1week"); // ending time TimeSpec specStart = pStart.parse(); TimeSpec specEnd = pEnd.parse(); long[] ts = TimeSpec.getTimestamps(specStart, specEnd);
- Parameters:
spec1
- Starting time specificationspec2
- Ending time specification- Returns:
- array containing two timestamps (in seconds since epoch)
