DateTimeUtils.DateTimeParseException - if the string cannot be parsed

See Also:

• Duration.parse(CharSequence)

parseDurationQuiet

@ScriptApi
@Nullable
public static @Nullable Duration parseDurationQuiet(@Nullable
 @Nullable String s)

Parses the string argument as a duration, which is a unit of time in terms of clock time (24-hour days, hours, minutes, seconds, and nanoseconds).

Duration strings are formatted according to the ISO-8601 duration format as [-]PnDTnHnMn.nS, where the coefficients can be positive or negative. Zero coefficients can be omitted. Optionally, the string can begin with a negative sign.

Examples:

    "PT20.345S" -- parses as "20.345 seconds"
    "PT15M"     -- parses as "15 minutes" (where a minute is 60 seconds)
    "PT10H"     -- parses as "10 hours" (where an hour is 3600 seconds)
    "P2D"       -- parses as "2 days" (where a day is 24 hours or 86400 seconds)
    "P2DT3H4M"  -- parses as "2 days, 3 hours and 4 minutes"
    "PT-6H3M"    -- parses as "-6 hours and +3 minutes"
    "-PT6H3M"    -- parses as "-6 hours and -3 minutes"
    "-PT-6H+3M"  -- parses as "+6 hours and -3 minutes"
 

Parameters:

s - duration string

Returns:

the duration, or null if the string can not be parsed
