2. (2) Probation for the current offense shall not be granted, nor shall execution or imposition of the sentence be suspended for any prior offense.
3. (3) The length of time between the prior serious or violent felony conviction and the current felony conviction shall not affect the imposition of sentence.

The determination of whether a prior conviction is a prior serious or violent felony conviction for purposes of this section shall be made upon the date of that prior conviction and is not affected by the sentence imposed unless the sentence automatically, upon the initial sentencing, converts the felony to a misdemeanor.

2.

(c) For purposes of this section, and in addition to any other enhancements or punishment provisions that may apply, the following apply if a defendant has one or more prior serious or violent felony convictions:

1. (1) If a defendant has one prior serious or violent felony conviction as defined in subdivision (b) that has been pled and proved, the determinate term or minimum term for an indeterminate term shall be twice the term otherwise provided as punishment for the current felony conviction.

2. (2)

   1. (A) Except as provided in subparagraph (C), if a defendant has two or more prior serious or violent felony convictions, as defined in subdivision (b), that have been pled and proved, the term for the current felony conviction shall be an indeterminate term of life imprisonment with a minimum term of the indeterminate sentence calculated as the greatest of any of the following:

   2. (B) The indeterminate term described in subparagraph (A) shall be served consecutive to any other term of imprisonment for which a consecutive term may be imposed by law. Any other term imposed subsequent to an indeterminate term described in subparagraph (A) shall not be merged therein but shall commence at the time the person would otherwise have been released from prison.

   3. (C) If a defendant has two or more prior serious or violent felony convictions as defined in subdivision (c) of Section 667.5 or subdivision (c) of Section 1192.7 that have been pled and proved, and the current offense is not a felony described in paragraph (1) of subdivision (b), the defendant shall be sentenced pursuant to paragraph (1) of subdivision (c), unless the prosecution pleads and proves any of the following:
