Instance Method Details

#to_hms ⇒ String

Formats time as “HH:MM:SS” (e.g. “23:59:59”). Equivalent to strftime(“%H:%M:%S”), but ~10% faster (or ~20% if the format string is an un-frozen literal, due to GC).

Returns:

• (String) —

  the time formatted as “HH:MM:SS”

def to_hms
  # Date#strftime appears to be **much** faster than Time#strftime
  # (nearly 3x faster!).  If Time#strftime becomes optimized to that
  # level in the future, it should be used instead of sprintf.
  sprintf('%02d:%02d:%02d'.freeze, hour, min, sec)
end

#to_ymd ⇒ String

Formats time as “YYYY-MM-DD” (e.g. “1999-12-31”). Equivalent to strftime(“%Y-%m-%d”), but ~6% faster (or ~18% if the format string is an un-frozen literal, due to GC).

Returns:

• (String) —

  the time formatted as “YYYY-MM-DD”
