Example 1 with MONTHS

use of java.time.temporal.ChronoUnit.MONTHS in project phoebus-olog by Olog.

the class TimeParser method parseTemporalAmount.

/**
 * Parse a temporal amount like "1 month 2 days" or "1 day 20 seconds"
 *
 *  <p>Provides either a time-based {@link Duration}
 *  or a calendar based {@link Period}.
 *
 *  <p>A period of "1 months" does not have a well defined
 *  length in time because a months could have 28 to 31 days.
 *  When the user specifies "1 month" we assume that
 *  a time span between the same day in different months
 *  is requested.
 *  As soon as the time span includes a month or year,
 *  a {@link Period} is returned and the smaller units
 *  from hours down are ignored.
 *
 *  <p>For time spans that only include days or less,
 *  a {@link Duration} is used.
 *
 *  @param string Text
 *  @return {@link Duration} or {@link Period}
