Peter Rajnoha ded279f826 report: add support for time (basic) ... This patch adds support for time values used in reporting fields. The raw values are always stored as number of seconds since epoch. The support that comes with this patch is the basic one which allows only for recognition of strictly formatted date and time in selection criteria (the format follows a subset of formats defined by ISO 8601): date time timezone date: YYYY-MM-DD (or shortly YYYYMMDD) YYYY-MM (shortly YYYYMM), auto DD=1 YYYY, auto MM=01 and DD=01 time: hh:mm:ss (or shortly hhmmss) hh:mm (or shortly hhmm), auto ss=0 hh (or shortly hh), auto mm=0, auto ss=0 timezone (always with + or - sign): +hh:mm or -hh:mm (or shortly +hhmm or -hhmm) +hh or -hh Or directly the time (number of seconds) since Epoch (1970-01-01 00:00:00 UTC) when the number value is prefixed by "@": @number_of_seconds_since_epoch This patch also adds aliases for comparison operators used together with time values which are more intuitive to use: since (as alias for >=) after (as alias for >) until (as alias for <=) before (as alias for <) For example: $ lvmconfig --type full report/time_format time_format="%Y-%m-%d %T %z %Z [%s]" $ lvs -o name,time vg LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol2 2015-04-26 14:52:20 +0200 CEST [1430052740] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] $ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30"' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] $ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30 6:00"' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] $ lvs vg -o name,time -S 'time since @1435519541' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] This is basic time recognition support that is directly a part of libdevmapper. Recognition of more free-form expressions will be a part of subsequent patches.		2015-06-30 15:15:10 +02:00
