Timestamp

Timestamp (or ConvertibleTimestamp) is a PHP library that provides a convenient wrapper around DateTime to create, parse, and format timestamps.

On input, the following formats are recognized:

• A subset of ISO 8601 basic and extended formats:
  • Years before 0000 or after 9999 are not supported.
  • Week and ordinal dates are not supported.
  • Accuracy to seconds is required. Fractions of a second are supported to microsecond resolution.
  • If the timezone is omitted, UTC is assumed.
  • As an extension, the 'T' may be replaced with a single space.
• As a signed integer (up to 13 digits) representing seconds since the Unix epoch.
  • Optionally with decimal seconds to microsecond resolution, using '.' as the decimal separator.
• RFC 2822 format, including obsolete syntax.
  • CFWS tokens are not fully supported, use only FWS.
  • Note, per the RFC, all military timezones are considered as -0000.
  • As an extension, the timezone may be omitted entirely in which case UTC is assumed.
  • As an extension, anything after the first semicolon in the string is ignored.
• RFC 850 format.
• asctime format.
• The TS_MW, TS_DB, TS_POSTGRES, TS_ORACLE, and TS_EXIF formats described below.

For output, the following conversions are predefined:

• TS_DB - MySQL datetime format: "2012-07-31 19:01:08"
• TS_EXIF - Exif 2.2 format: "2012:07:31 19:01:08"
• TS_ISO_8601 - ISO 8601 expanded format: "2012-07-31T19:01:08Z"
• TS_ISO_8601_BASIC - ISO 8601 basic format: "20120731T190108Z"
• TS_MW - A 14-digit string: "20120731190108"
• TS_ORACLE - A default Oracle timestamp format: "31-07-2012 19:01:08.000000"
• TS_POSTGRES - PostgreSQL default timestamptz format: "2012-07-31 19:01:08+00"
• TS_RFC2822 - RFC 2822 format using an obsolete timezone: "Tue, 31 Jul 2012 19:01:08 GMT"
• TS_UNIX - Seconds since the Unix epoch (1970-01-01T00:00:00Z): "1343761268"
• TS_UNIX_MICRO - Seconds since the Unix epoch with microseconds: "1343761268.000000"
