Introduction

Freeside stores most dates as "Unix time" - the number of seconds elapsed since midnight UTC on the morning of January 1, 1970, not counting leap seconds.

Conversion in Perl

  • Conversion from UNIX time: see the localtime function or the Date::Format module.
  • Conversion to UNIX time: see the Date::Parse or Time::Local modules, among others.

Conversion in PostgreSQL

  • Conversion from UNIX time (substitute in your own time zone, date field and output field name): 


'epoch'::TIMESTAMP WITH TIME ZONE AT TIME ZONE 'PST' + _date_field * '1 second'::INTERVAL AS output_fieldname




Conversion in Crystal Reports


  •  Download the U2lwin32 user function library
    • 

  •  Use the provided "EpochToDateTime" function
    • 

  •  Works with Crystal Reports 11 by manually installing the U2lwin32.dll to Business Objects\Common\3.5\bin
