  Methods:
  • FormatDateRange (StartTicks As Long, EndTicks As Long, Flags As Int) As String
    Formats a date or a time range according to the local conventions.
    
    Note that this is a convenience method. Using it involves creating an
    internal Formatter instance on-the-fly, which is somewhat costly in terms
    of memory and time.
    
    StartTicks - start time
    EndTicks - end time
    Flags - a bit mask of options
  • FormatDateTime (Ticks As Long, Flags As Int) As String
    Formats a date or a time according to the local conventions. There are
    lots of options that allow the caller to control, for example, if the
    time is shown, if the day of the week is shown, if the month name is
    abbreviated, if noon is shown instead of 12pm, and so on.
    
    Ticks - time/date to format
    Flags - a bit mask of options
  • FormatElapsedTime (Seconds As Long) As String
    Formats an elapsed time in the form "MM:SS" or "H:MM:SS" for display on
    the call-in-progress screen.
    
    Seconds - the elapsed time in seconds.
  • GetRelativeDateTimeString (Ticks As Long, MinResolution As Long, TransitionResolution As Long, Flags As Int) As CharSequence
    Return string describing the elapsed time since startTime formatted like
    "[relative time/date], [time]".
    
    <b>Ticks</b> - some time in the past.
    
    <b>MinResolution</b> - the minimum elapsed time (in milliseconds) to
    report when showing relative times. For example, a time 3 seconds in the
    past will be reported as "0 minutes ago" if this is set to
    MINUTE_IN_MILLIS.
    
    <b>TransitionResolution</b> - the elapsed time (in milliseconds) at which
    to stop reporting relative measurements. Elapsed times greater than this
    resolution will default to normal date formatting. For example, will
    transition from "6 days ago" to "Dec 12" when using WEEK_IN_MILLIS.
    
    <b>Flags</b> - a bit mask of options
  • GetRelativeTimeSpanString (Ticks As Long, Now As Long, MinResolution As Long, Flags As Int) As CharSequence
    Returns a string describing 'time' as a time relative to 'now'.
    
    Time spans in the past are formatted like "42 minutes ago". Time spans in
    the future are formatted like "in 42 minutes". Can use
    FORMAT_ABBREV_RELATIVE flag to use abbreviated relative times, like
    "42 mins ago".
    
    <b>Ticks</b> - the time to describe, in milliseconds
    
    <b>Now</b> - the current time in
    milliseconds
    
    <b>MinResolution</b> - the minimum timespan to report. For example,
    a time 3 seconds in the past will be reported as "0 minutes ago" if this
    is set to MINUTE_IN_MILLIS. Pass one of 0, MINUTE_IN_MILLIS,
    HOUR_IN_MILLIS, DAY_IN_MILLIS, WEEK_IN_MILLIS
    
    <b>Flags</b> - a bit mask of
    formatting options, such as FORMAT_NUMERIC_DATE or FORMAT_ABBREV_RELATIVE

    The base implementation returns 3600000 (1 hour) for time zones that use daylight savings
    time and 0 for timezones that do not.
    Note that this method doesn't tell you whether or not to apply the offset: you need to call
    InDaylightTime() for the specific time you're interested in. If this method returns a non-zero
    offset, that only tells you that this TimeZone sometimes observes daylight savings.

    added to the missing translation table and the original text is returned.
    So you can write your whole program in a default language. If a
    translation is available it will be used, if not, the text will be
    returned in the default language.
  • GetText2 (text As String, params As List) As String
    Searches for the text in the translation table and returns the translated
    text.
