Defined in:
lib/rasn1/types/generalized_time.rb

Overview

ASN.1 GeneralizedTime

+Base#value of a GeneralizedTime should be a ruby Time.

Notes

When encoding, resulting string is always a UTC time, appended with Z. Minutes and seconds are always generated. Fractions of second are generated if value Time object have them.

On parsing, are supported:

  • UTC times (ending with Z),

  • local times (no suffix),

  • local times with difference between UTC and this local time (ending with sHHMM, where s is +++ or -, and HHMM is the time differential betwen UTC and local time).

These times may include minutes and seconds. Fractions of hour, minute and second are supported.
