qdate

Small, light and quick handy date conversion functions.

Unlike timezone packages that drag along their own timezone database, qdate leverages the host system's native timezone support, making it much smaller.

This is a work in progress.

Summary

var qdate = require('qdate')
qdate.adjust(new Date(), -30, 'minute');

Api

abbrev( tzName ), getTimezoneAbbrev

return the three-character timezone abbreviation of the named timezone

offset( tzName ), getTimezoneOffset

return the offset as minutes west of GMT of the named timezone. This is what new Date().getTimezoneOffset() does for the default timezone.

list( ), getTimezoneList

return the list of known timezone names as an array of strings

adjust( timestamp, delta, units )

return the Date corresponding to the timestamp adjusted by +/- delta units. Units may be one of 'year', 'month', 'week', 'day', 'hour', 'minute' or 'second' or 'millisecond'.

strtotime( timespec [,tzName] )

convert the time specification to a Date. The time spec can be anything date --date can parse, like "+2 hours" or "3 weeks ago" or "9pm last Friday".

? format( timestamp [,tzName] )

format the timestamp in the named timezone locale. Formatting by phpdate

? convert( timestamp, tzFromName, tzToName, [format] )

convert the timestamp between timezones, and return a reformatted timestamp. Formatting by phpdate

? startOf( timestamp, unit )

return the Date corresponding to the timestamp at the start of the named unit. Unit can be any time division listed under adjust() above, eg 'month', 'week', 'hour'.
