Article contents:[[tags: manual]] [[toc:]] == Module (chicken time posix) This module provides procedures for conversion between seconds since the epoch ("POSIX time"), strings and a 10-element vector type containing the distinct time units. === seconds->local-time <procedure>(seconds->local-time [SECONDS])</procedure> Breaks down the time value represented in {{SECONDS}} into a 10 element vector of the form {{#(seconds minutes hours mday month year wday yday dstflag timezone)}}, in the following format: ; seconds (0) : the number of seconds after the minute (0 - 59) ; minutes (1) : the number of minutes after the hour (0 - 59) ; hours (2) : the number of hours past midnight (0 - 23) ; mday (3) : the day of the month (1 - 31) ; month (4) : the number of months since january (0 - 11) ; year (5) : the number of years since 1900 ; wday (6) : the number of days since Sunday (0 - 6) ; yday (7) : the number of days since January 1 (0 - 365) ; dstflag (8) : a flag that is true if Daylight Saving Time is in effect at the time described. ; timezone (9) : the difference between UTC and the latest local standard time, in seconds west of UTC. {{SECONDS}} defaults to the value of {{(current-seconds)}}. === local-time->seconds <procedure>(local-time->seconds VECTOR)</procedure> Converts the ten-element vector {{VECTOR}} representing the time value relative to the current timezone into the number of seconds since the first of January, 1970 UTC. === local-timezone-abbreviation <procedure>(local-timezone-abbreviation)</procedure> Returns the abbreviation for the local timezone as a string. === seconds->string <procedure>(seconds->string [SECONDS])</procedure> Converts the time represented in {{SECONDS}} into a local-time string of the form {{"Tue May 21 13:46:22 1991"}}. {{SECONDS}} defaults to the value of {{(current-seconds)}}. === seconds->utc-time <procedure>(seconds->utc-time [SECONDS])</procedure> Similar to {{seconds->local-time}}, but interpretes {{SECONDS}} as UTC time. {{SECONDS}} defaults to the value of {{(current-seconds)}}. === utc-time->seconds <procedure>(utc-time->seconds VECTOR)</procedure> Converts the ten-element vector {{VECTOR}} representing the UTC time value into the number of seconds since the first of January, 1970 UTC. '''NOTE''': On native Windows builds (all except cygwin), this procedure is unimplemented and will raise an error. === time->string <procedure>(time->string VECTOR [FORMAT])</procedure> Converts the broken down time represented in the 10 element vector {{VECTOR}} into a string of the form represented by the {{FORMAT}} string. The default time form produces something like {{"Tue May 21 13:46:22 1991"}}. The {{FORMAT}} string follows the rules for the C library procedure {{strftime}}. The default {{FORMAT}} string is {{"%a %b %e %H:%M:%S %Z %Y"}}. === string->time <procedure>(string->time TIME [FORMAT])</procedure> Converts a string of the form represented by the {{FORMAT}} string into the broken down time represented in a 10 element vector. The default time form understands something like {{"Tue May 21 13:46:22 1991"}}. The {{FORMAT}} string follows the rules for the C library procedure {{strptime}}. The default {{FORMAT}} string is {{"%a %b %e %H:%M:%S %Z %Y"}}. --- Previous: [[Module (chicken time)]] Next: [[Module (chicken type)]] Description of your changes:
