Constant Summary collapse

UNITMAP =

How we convert from various units to seconds.

{
  # 365 days isn't technically a year, but is sufficient for most purposes
  "y" => 365 * 24 * 60 * 60,
  "d" => 24 * 60 * 60,
  "h" => 60 * 60,
  "m" => 60,
  "s" => 1
}
FORMAT =

A regex describing valid formats with groups for capturing the value and units

/^(\d+)(y|d|h|m|s)?$/
