---++ StaticMethod *parseTime* <tt>($szDate,$defaultLocal) -> $iSecs</tt>
|
|
|
|
Convert string date/time string to seconds since epoch (1970-01-01T00:00:00Z).
|
|
* =$sDate= - date/time string
|
|
|
|
Handles the following formats:
|
|
* 31 Dec 2001 - 23:59
|
|
* 2001/12/31 23:59:59
|
|
* 2001.12.31.23.59.59
|
|
* 2001/12/31 23:59
|
|
* 2001.12.31.23.59
|
|
* 2001-12-31T23:59:59
|
|
ISO dates may have a timezone specifier, either Z or a signed difference
|
|
in hh:mm format. For example:
|
|
* 2001-12-31T23:59:59+01:00
|
|
* 2001-12-31T23:59Z
|
|
The default timezone is Z, unless $defaultLocal is true in which case
|
|
the local timezone will be assumed.
|
|
|
|
If the date format was not recognised, will return 0.

---++ StaticMethod *formatTime* <tt>($epochSeconds,$formatString,$outputTimeZone) -> $value</tt>
|
|
|
|
* =$epochSeconds= epochSecs GMT
|
|
* =$formatString= twiki time date format, default =$day $month $year - $hour:$min=
|
|
* =$outputTimeZone= timezone to display, =gmtime= or =servertime=, default is whatever is set in $TWiki::cfg{DisplayTimeValues}
|
|
=$formatString= supports:
|
|
| $seconds | secs |
|
|
| $minutes | mins |
|
|
| $hours | hours |
|
|
| $day | date |
|
|
| $wday | weekday name |
|
|
| $dow | day number (0 = Sunday) |
|
|
| $week | week number |

|
---++ StaticMethod *formatDelta* <tt>($s) -> $string</tt>
|
|
|
|
Format a time in seconds as a string. For example,
|
|
"1 day, 3 hours, 2 minutes, 6 seconds"
|
|
|
|
|
|
|
|
---++ StaticMethod *parseInterval* <tt>($szInterval) -> [$iSecs,$iSecs]</tt>
|
|
|
|
Convert string representing a time interval to a pair of integers
|
|
representing the amount of seconds since epoch for the start and end
|
|
extremes of the time interval.
|
|
|
|
* =$szInterval= - time interval string
|
|
|
|
in yacc syntax, grammar and actions:
|
|
<verbatim>
|
|
interval ::= date { $$.start = fillStart($1); $$.end = fillEnd($1); }
|
|
| date '/' date { $$.start = fillStart($1); $$.end = fillEnd($3); }
|
|
| 'P' duration '/' date { $$.start = fillEnd($4)-$2; $$.end = fillEnd($4); }
|
|
| date '/' 'P' duration { $$.start = fillStart($1); $$.end = fillStart($1)+$4; }
|
|
;
|
|
</verbatim>
|
|
an =interval= may be followed by a timezone specification string (this is not supported yet).
|
|
|
|
=duration= has the form (regular expression):
|
|
<verbatim>
|
|
P(<number><nameOfDuration>)+
|
|
</verbatim>
|
|
|
|
nameOfDuration may be one of:
|
|
* y(year), m(month), w(week), d(day), h(hour), M(minute), S(second)
|
|
|
|
=date= follows ISO8601 and must include hypens. (any amount of trailing
|
|
elements may be omitted and will be filled in differently on the
|
|
differents ends of the interval as to include the longest possible
|
|
interval):
|
|
|
|
* 2001-01-01T00:00:00
|
|
* 2001-12-31T23:59:59
|
|
|
|
timezone is optional. Default is local time.
|
|
|
|
If the format is not recognised, will return empty interval [0,0].
