org.apache.poi.hslf.util.SystemTimeUtils

public final class SystemTimeUtils
extends Object

A helper class for dealing with SystemTime Structs, as defined at http://msdn.microsoft.com/library/en-us/sysinfo/base/systemtime_str.asp . Discrepancies between Calendar and SYSTEMTIME: - that January = 1 in SYSTEMTIME, 0 in Calendar. - that the day of the week (0) starts on Sunday in SYSTEMTIME, and Monday in Calendar It is also the case that this does not store the timezone, and no... it is not stored as UTC either, but rather the local system time (yuck.)
