unix-timestamp

Tiny library to create and manipulate Unix timestamps in Javascript. (A Unix timestamp is the number of seconds elapsed since Unix epoch time, i.e. January 1 1970 00:00 UTC.)

Usage

Install with npm install unix-timestamp, then:

• timestamp.now([delta]) gives the current time, optionally applying a delta (see below)
• timestamp.fromDate(dateOrString) gives the time from a Javascript Date object or an ISO 8601 date string
• timestamp.toDate(time) correspondingly gives the date from a timestamp
• timestamp.add(time, delta) applies a delta to the given time
• timestamp.duration(delta) gives the delta timestamp for the given delta string

A delta can be either a number (unit: seconds) or a string with format [+|-] [{years}y] [{months}M] [{weeks}w] [{days}d] [{hours}h] [{minutes}m] [{seconds}s] [{milliseconds}ms] (for example -30s). The actual values (in seconds) used for each unit of time are accessible in properties Millisecond, Second, Minute, Hour, Day, Week, Month (i.e. mean Gregorian month) and Year.

By default timestamps include decimals (fractions of a second). You can set the lib to round all returned timestamps to the second with timestamp.round = true.
