  7. formatTime :: FormatTime t => TimeLocale -> String -> t -> String

    time Data.Time.Format.Internal

    Substitute various time-related information for each %-code in the string, as per formatCharacter. The general form is %<modifier><width><alternate><specifier>, where <modifier>, <width>, and <alternate> are optional.

    <modifier>

    glibc-style modifiers can be used before the specifier (here marked as z):
    • %-z no padding
    • %_z pad with spaces
    • %0z pad with zeros
    • %^z convert to upper case
    • %#z convert to lower case (consistently, unlike glibc)

    <width>

    Width digits can also be used after any modifiers and before the specifier (here marked as z), for example:
    • %4z pad to 4 characters (with default padding character)
    • %_12z pad with spaces to 12 characters

    <alternate>

    An optional E character indicates an alternate formatting. Currently this only affects %Z and %z.
    • %Ez alternate formatting

    <specifier>

    For all types (note these three are done by formatTime, not by formatCharacter):
    • %% %
    • %t tab
    • %n newline

    TimeZone

    For TimeZone (and ZonedTime and UTCTime):
    • %z timezone offset in the format ±HHMM
    • %Ez timezone offset in the format ±HH:MM
    • %Z timezone name (or else offset in the format ±HHMM)
    • %EZ timezone name (or else offset in the format ±HH:MM)

    LocalTime

    For LocalTime (and ZonedTime and UTCTime and UniversalTime):
    • %c as dateTimeFmt locale (e.g. %a %b %e %H:%M:%S %Z %Y)

    TimeOfDay

    For TimeOfDay (and LocalTime and ZonedTime and UTCTime and UniversalTime):
    • %R same as %H:%M
    • %T same as %H:%M:%S
    • %X as timeFmt locale (e.g. %H:%M:%S)
    • %r as time12Fmt locale (e.g. %I:%M:%S %p)
    • %P day-half of day from (amPm locale), converted to lowercase, am, pm
    • %p day-half of day from (amPm locale), AM, PM
    • %H hour of day (24-hour), 0-padded to two chars, 00 - 23
    • %k hour of day (24-hour), space-padded to two chars, 0 - 23
    • %I hour of day-half (12-hour), 0-padded to two chars, 01 - 12
    • %l hour of day-half (12-hour), space-padded to two chars, 1 - 12
    • %M minute of hour, 0-padded to two chars, 00 - 59
    • %S second of minute (without decimal part), 0-padded to two chars, 00 - 60
    • %q picosecond of second, 0-padded to twelve chars, 000000000000 - 999999999999.
    • %Q decimal point and fraction of second, up to 12 second decimals, without trailing zeros. For a whole number of seconds, %Q omits the decimal point unless padding is specified.

    UTCTime and ZonedTime

    For UTCTime and ZonedTime:
    • %s number of whole seconds since the Unix epoch. For times before the Unix epoch, this is a negative number. Note that in %s.%q and %s%Q the decimals are positive, not negative. For example, 0.9 seconds before the Unix epoch is formatted as -1.1 with %s%Q.

    DayOfWeek

    For DayOfWeek (and Day and LocalTime and ZonedTime and UTCTime and UniversalTime):
    • %u day of week number for Week Date format, 1 (= Monday) - 7 (= Sunday)
    • %w day of week number, 0 (= Sunday) - 6 (= Saturday)
    • %a day of week, short form (snd from wDays locale), Sun - Sat
    • %A day of week, long form (fst from wDays locale), Sunday - Saturday

    Month

    For Month (and Day and LocalTime and ZonedTime and UTCTime and UniversalTime):
    • %Y year, no padding. Note %0Y and %_Y pad to four chars
    • %y year of century, 0-padded to two chars, 00 - 99
    • %C century, no padding. Note %0C and %_C pad to two chars
    • %B month name, long form (fst from months locale), January - December
    • %b, %h month name, short form (snd from months locale), Jan - Dec
    • %m month of year, 0-padded to two chars, 01 - 12

    Day

    For Day (and LocalTime and ZonedTime and UTCTime and UniversalTime):
    • %D same as %m/%d/%y
    • %F same as %Y-%m-%d
    • %x as dateFmt locale (e.g. %m/%d/%y)
    • %d day of month, 0-padded to two chars, 01 - 31
    • %e day of month, space-padded to two chars, 1 - 31
    • %j day of year, 0-padded to three chars, 001 - 366
    • %f century for Week Date format, no padding. Note %0f and %_f pad to two chars
    • %V week of year for Week Date format, 0-padded to two chars, 01 - 53
    • %U week of year where weeks start on Sunday (as sundayStartWeek), 0-padded to two chars, 00 - 53
    • %W week of year where weeks start on Monday (as mondayStartWeek), 0-padded to two chars, 00 - 53

    Duration types

    The specifiers for DiffTime, NominalDiffTime, CalendarDiffDays, and CalendarDiffTime are semantically separate from the other types. Specifiers on negative time differences will generally be negative (think rem rather than mod).

    NominalDiffTime and DiffTime

    Note that a "minute" of DiffTime is simply 60 SI seconds, rather than a minute of civil time. Use NominalDiffTime to work with civil time, ignoring any leap seconds. For NominalDiffTime and DiffTime:
    • %w total whole weeks
    • %d total whole days
    • %D whole days of week
    • %h total whole hours
    • %H whole hours of day
    • %m total whole minutes
    • %M whole minutes of hour
    • %s total whole seconds
    • %Es total seconds, with decimal point and up to <width> (default 12) decimal places, without trailing zeros. For a whole number of seconds, %Es omits the decimal point unless padding is specified.
    • %0Es total seconds, with decimal point and <width> (default 12) decimal places.
    • %S whole seconds of minute
    • %ES seconds of minute, with decimal point and up to <width> (default 12) decimal places, without trailing zeros. For a whole number of seconds, %ES omits the decimal point unless padding is specified.
    • %0ES seconds of minute as two digits, with decimal point and <width> (default 12) decimal places.

    CalendarDiffDays

    For CalendarDiffDays (and CalendarDiffTime):
    • %y total years
    • %b total months
    • %B months of year
    • %w total weeks, not including months
    • %d total days, not including months
    • %D days of week

    CalendarDiffTime

    For CalendarDiffTime:
    • %h total hours, not including months
    • %H hours of day
    • %m total minutes, not including months
    • %M minutes of hour
    • %s total whole seconds, not including months
    • %Es total seconds, not including months, with decimal point and up to <width> (default 12) decimal places, without trailing zeros. For a whole number of seconds, %Es omits the decimal point unless padding is specified.
    • %0Es total seconds, not including months, with decimal point and <width> (default 12) decimal places.
    • %S whole seconds of minute
    • %ES seconds of minute, with decimal point and up to <width> (default 12) decimal places, without trailing zeros. For a whole number of seconds, %ES omits the decimal point unless padding is specified.
    • %0ES seconds of minute as two digits, with decimal point and <width> (default 12) decimal places.

  8. formatError :: JSONPath -> String -> String

    aeson Data.Aeson.Types
