OPINION
RACANELLI, P.J. 

III. Worktime Credits[*]
(1a) Defendant was sentenced to 4 years in prison with credit for time served (128 days) and good time/work time (64 days). Defendant now contends he should have been given additional credits under the new worktime credits provided under Penal Code section 2933.
The contention is faulty for several reasons. Penal Code section 2933 establishes a new program of worktime credits for prison inmates alone. (2) The obvious purpose of the statutory program is to provide incentives for prisoners to work in one of the new prison industries and thereby to *255 develop job skills and work ethics. (Stats. 1982, ch. 1, § 1, p. 1; Pen. Code, §§ 2800, 2801 [Prison Industry Authority created to operate various industrial, agricultural and service enterprises employing prisoners].) Such valid statutory objectives have no relevance to pretrial detainees.
(1b) Defendant's reliance on People v. Sage (1980) 26 Cal.3d 498 [165 Cal. Rptr. 280, 611 P.2d 874] [good time credits uniformly available to sentenced prisoners and pretrial detainees on equal protection grounds] is misplaced. Sage extended good time credits to pretrial detainee felons as being similarly situated to prison inmates and pretrial detainee misdemeanants receiving such credit by statutory provision. In contrast, the statute here applies only to prison inmates. Pretrial detainees are not similarly situated; since they do not stand convicted of a crime, no need arises to provide work incentives for purposes of rehabilitation. (Cf. People v. Olivas (1976) 17 Cal.3d 236, 247, fn. 15 [131 Cal. Rptr. 55, 551 P.2d 375] ["[T]he state [cannot] presume to rehabilitate persons clothed in the presumption of innocence."].) Moreover, we may judicially notice that county detention facilities are unable to provide job programs similar to the extensive industries run by the state prison system.
Finally, the statutory worktime credits program became effective January 1, 1983. (See In re Strick (1983) 148 Cal. App.3d 906 [196 Cal. Rptr. 293].) Since defendant was sentenced to prison on January 3, 1983, his two days of presentence custody would have no effect on his release date assuming, arguendo, the claimed credits applied.
Judgment affirmed.
Elkington, J., and Holmdahl, J., concurred.
