DESCRIPTION

API

monthsToInt ($$)

convert from english/german/custom locale short months -> numbers, monthsToInt("Oct","en") equals 10, monthsToInt("mär","ge") equals 3. months and locale are case insensitive.

$mon ..  month in textual format (as defined in locale)
$locale .. locale as defined in monthsToInt (builtin "en" and "ge", can be added with addLocaleMonths)

intToMonths ($$)

convert from int to english/german/custom locale months -> numbers, intToMonths(10,"en") equals "Oct", intToMonths(3,"ge") equals "Mär". locale is case insensitive, month is returned with first letter uppercase resp. as it was added (see below).

$mon ..  month in textual format (as defined in locale)
$locale .. locale as defined in monthsToInt (builtin "en" and "ge", can be added with addLocaleMonths)

addLocaleMonths ($$)

adds custom locale $locale with ref to array $monthsArray to above conversion functions. locale is case insensitive.

$locale .. locale to be defined
$months .. ref to array of months in textual format

Example:

addLocaleMonths("fr",["Jan","Fév","Mars","Mai","Juin","Juil","Août","Sept","Oct","Nov","Déc"]);

get_curdate

gets current date in format YYYYMMDD

get_curdatetime

gets current datetime in format YYYYMMDD_HHMMSS

get_curdate_dot

gets current date in format DD.MM.YYYY

formatDate ($$$;$)

formats passed date (given in arguments $y,$m,$d) into format as defined in $template

$y .. year part
$m .. month part
$d .. day part
$template .. optional, date template with D for day, M for month and Y for year (e.g. D.M.Y for 01.02.2016),
             D and M is always 2 digit, Y always 4 digit; if empty/nonexistent defaults to "YMD"
             special formats are MMM und mmm als monthpart, here three letter month abbreviations in english (MMM) or german (mmm) are returned as month
             additionally a locale can be passed in brackets with MMM and mmm, resulting in conversion to locale dependent months.
             e.g. formatDate(2002,6,1,"Y-MMM-D[fr]") would yield 2002-Juin-01 for the addLocaleMonths given above.

formatDateFromYYYYMMDD ($;$)

$date .. date in format YYYYMMDD
$template .. same as in formatDate above

get_curdate_dash_plus_X_years ($;$$)

$y .. years to be added to the current or given date
$date .. optional date to which X years should be added (if not given, then current date is taken instead).
$daysToSubtract .. optional days that should be subtracted from above result

get_curtime_epochs

returns current time in epochs as from builtin function time()

get_curtime (;$$)
